Binomial Probability 1. Assume a hotel has 5 elevators and one of the elevators is a freight elevator. When pressing the elevator button, one of the elevators randomly services your floor. Assume you use the elevator eight times during your stay at the hotel. a. What is the probability you will use the freight elevator exactly 3 times? The following equation will assist you in solving this problem. ()pk (1-p)n-k. b. What is the probability you will use the freight elevator at most 3 times? The following equation will assist you in solving this problem. ()pk(1-p)n-k.

![**Binomial Probability**
1. Assume a hotel has 5 elevators and one of the elevators is a freight elevator. When pressing the elevator button, one of the elevators randomly services your floor. Assume you use the elevator eight times during your stay at the hotel.
a. What is the probability you will use the freight elevator exactly 3 times? The following equation will assist you in solving this problem.
\[
\binom{n}{k}p^k(1 - p)^{n-k}
\]
b. What is the probability you will use the freight elevator at most 3 times? The following equation will assist you in solving this problem.
\[
\binom{n}{k}p^k(1 - p)^{n-k}
