Question

Career Fair Attendance For a Nursing and Allied Health Care Career Fair, organizers estimate that 50 people will attend if it does not rain and 65 will attend if it rains. The weather forecast indicates that there is a 40% chance it will not rain and a 60% chance it will rain on the day of the career fair. Determine the expected number of people who will attend the fair.

Answer 1

Here, we find the expected value (number) of people who may attend
It is sum of product of probabilities and number of people for no rain and rain condition
=0.4(50)+0.6(65)
= 59
59 people may be expected to attend.
