The answer is the polygon have 24 sides.

Solution is shown step by step: Let c be the 15 degrees.

1. C = 360 divided by n

2. 15 = 360 divided by n

3. then transpose n to the other side
    15n = 360

4. divide both sides by 15
    n = 360 divided by 15

5. n = 24

One day, thirteen babies are born at a hospital. assuming each baby has an equal chance of being a boy or girl, what is the prob
Nadya [2.5K]

Using the binomial distribution, there is a 0.9983 = 99.83% probability that at most eleven of the thirteen babies are girls.

<h3>What is the binomial distribution formula?</h3>

The formula is:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

For this problem, the values of the parameters are:

p = 0.5, n = 13

The probability that at most eleven of the thirteen babies are girls is:

P(X \leq 11) = 1 - P(X > 11)

In which

P(X > 11) = P(X = 12) + P(X = 13)

Then:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 12) = C_{13,12}.(0.5)^{12}.(0.5)^{1} = 0.0016

P(X = 13) = C_{13,13}.(0.5)^{13}.(0.5)^{0} = 0.0001

So:

P(X > 11) = P(X = 12) + P(X = 13) = 0.0016 + 0.0001 = 0.0017

P(X \leq 11) = 1 - P(X > 11) = 1 - 0.0017 = 0.9983

0.9983 = 99.83% probability that at most eleven of the thirteen babies are girls.
