If you flip a fair coin 777 times, what is the probability that you will get exactly 222 tails?

There is a less than 16.41% probability that you will get exactly 2 tails.

Step-by-step explanation:

For each time you flip a coin, there are only two possible outcomes. Either it is heads, or it is tails. This means that we use the binomial probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.

In this problem we have that:

What is the probability that you will get exactly 2 tails?

This is P(X = 2).

There is a less than 16.41% probability that you will get exactly 2 tails.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
