In this lesson, students gain more practice using while loops as they develop a simulation that repeatedly flips coins until certain conditions are met. The lesson begins with an unplugged activity in which students flip a coin until they get 5 heads in total, and then again until they get 3 heads in a row.

They will then compete to predict the highest outcome in the class for each statistic. This activity motivates the programming component of the lesson in which students develop a program that allows them to simulate this experiment for higher numbers of heads and longer streaks. The ability to model and simulate real-world phenomena on a computer has changed countless fields.

Researchers use simulations to predict the weather, the stock market, or the next viral outbreak. Scientists from all disciplines increasingly rely on computer simulation, rather than real-life experiments, to rapidly test their hypotheses in simulated environments. Programmers might simulate users moving across their sites to ensure they can handle spikes in traffic, and of course videogame and virtual reality technology is built around the ability to simulate some aspects of the real world.

The speed and scale at which simulations allow ideas to be tested and refined has had far-reaching impact, and it will only continue to grow in importance as computing power and computational models improve.

Differentiation and other adjustments to this lesson. Flip a coin until you get 5 total heads. Then again until you get 3 heads in a row. Record your results and predict the highest result in the class. Run a simple experiment by hand that it would be unmanageable to run on a larger scale, thus motivating the need to simulate it on a computer. Experiment 1: Groups will flip their coins as many times as it takes in order to get 5 heads total. Collect worksheets or just have students share answers to determine how accurate guesses were.

Perhaps offer small prizes for the group whose guesses were most accurate. That was pretty interesting with only 5 total heads or a streak of 3 heads. On the second part of their worksheets, students are asked to extend their hypotheses to try to predict how long it might take to flip 10, heads or find a streak of 20 heads.

Their actual predictions are less important than whether they demonstrate having reflected on the outcomes of the earlier simulation.

Simulations are an increasingly important tool for a variety of disciplines. Weather and traffic predictions are based on computer models that simulate weather patterns or people moving through a city. Scientific research, whether in physics, chemistry, or biology, increasingly uses simulations to develop new hypotheses and test ideas before spending the time and money to run a live experiment.

Before you use most of your favorite websites and apps, they will be tested by simulating high levels of traffic moving across the server. As computers get ever faster and models improve, we are able to answer old questions more quickly and start asking new ones.

The series of problems and tasks in this lesson progressively build up a series of experiments that simulate coin flipping. We ask students to make a hypothesisthen experiment with code, revise the hypothesis and so on, around some question. Below are some guidelines about what students should find. Total Heads: When trying to flip 5 heads, it is quite possible that it will only take 5 flips, but it may also easily take 15 or Relative to the number of heads you are looking for, this is a massive range!

When you are trying to flip 10, heads the likely range is typically between 19, and 21, and typically much closer. As you are looking for more flips, the relative width of the likely window shrinks. Longest Streak: When trying to find a streak of 3 heads it will typically take between 3 it's always possible!

Even slightly longer streaks of heads, however, will rapidly increase the average time it takes to find that streak. Looking for a streak of 12 heads might occasionally happen in fewer than flips, but it can also easily take tens of thousands.In this lesson, students gain more practice using while loops as they develop a simulation that repeatedly flips coins until certain conditions are met.

### Lesson 12: Loops and Simulations

The problem is that I also want to print the total number of heads and tails. I've been racking my brain for a solution and so far I have nothing. Is there any way to get the number of heads and tails printed in addition to the total number of tosses? You have a variable for the number of tries, which allows you to print that at the end, so just use the same approach for the number of heads and tails. You could use random.

Think about what you want accomplished: "I want a sequence of coin flips; I want an output of 'Heads' or 'Tails' for each one in order; I want to display a count of the heads and of the tails".

There are good ones, and then there are also bad ones.

The CS:GO coin flip game is a very simple and popular game. You start by depositing items into the website. Some sites are different and require you to deposit your items to make them into coins first, whereas other sites just take your skins right when you make the bet.

The coin then flips after some seconds. If the coin flips and lands on your symbol then you have won, and will be paid out the whole pot. However, if the coin flips and lands on the symbol that is NOT yours, then you have lost, and will get nothing in return. There are many reasons why this game has become as popular as it is today. Another reason is the adrenaline rush and excitement you get when you play this game. When you get matched with a player you can see his avatar and his actual Steam name.

This is dangerous because this is super addicting, and which is why you need to be careful when gambling online.

A third reason is probably the fact that you can double your whole inventory in a few seconds if you are lucky. This game is also one of those games where you typically get some of the best odds possible compared to other casino games. This, of course, depends on where you play this game mode, as it can be different from site to site.

After a lot of research, Little Elephant came to know that most of the animals in the forest were showing less interest to play the multi-player games.

In this game the player will use N coins numbered from 1 to Nand all the coins will be facing in "Same direction" Either Head or Tail ,which will be decided by the player before starting of the game. The player needs to play N rounds. In the k -th round the player will flip the face of the all coins whose number is less than or equal to k.

Elephant needs to guess the total number of coins showing a particular face after playing N rounds. Please help the Elephant to find out the answer. The first line of input contains an integer Tdenoting the number of test cases.

Then T test cases follow. The first line of each test contains an integer Gdenoting the number of games played by Elephant. Each of the following G lines denotes a single game, and contains 3 space separeted integers INQwhere I denotes the initial state of the coins, N denotes the number of coins and rounds, and Qwhich is either 1, or 2 as explained below.

For each game, output one integer denoting the total number of coins showing the particular face in the end of the game. In the 2nd game in Example: This is similar to the 1st game, except Elephant needs to find the total number of coins showing Tail. So the Answer is 3. Please see the final state of the coins in the 1st game.
