Using the binomial distribution, it is found that there is a 0.0231 = 2.31% probability that the first person to say yes will occur with the seventh customer.
For each person, there are only two possible outcomes, either they say yes, or they say no. The probability of a person saying yes is independent of any other person, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
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.
In this problem:
- The probability that the seventh person is the first to say yes is P(X = 0) when n = 6(first six say no) multiplied by 0.37(probability the seventh say yes).
- 37% say yes, hence
Then:
0.0231 = 2.31% probability that the first person to say yes will occur with the seventh customer.

Answer:
The second leg of the right triangle is about 9.4.
<em><u>Answer:</u></em>
115 is between 114 and 116 because they are the integers that are directly bigger than 115 and smaller than 115.
