Question

1. The chance of contracting the flu when coming into contact with an infected person is estimated to be 35%. Suppose that a family of five comes into contact with an infected person. Using a simulation answer the following questions.

a. What is the expected number of people in the family that will contract the flu?

Answer 1

Expect 2 family members to contract the flu.
The number of people that contract the flu with a set of 1 person is 0.35, because 35% x 1 = 0.35

35% of 5 people is 1.75 people, so you can expect 2 people to contract the flu as 1.75 rounded to the nearest whole number is 2.
