Question

A certain region has a population of 6.7 million. On any given​ day, the probability is StartFraction 1 Over 5000 EndFraction that a randomly selected resident decides to visit a certain amusement park. a. What is the probability that all the residents will decide to go​ tomorrow? b. What assumptions did you need to make to find that​ probability?

Answer 1

a. Very close to zero.

b. All people in the region are equally likely to decide to visit the amusement park on any given day.

Step-by-step explanation:

Assuming that all people in the region are equally likely to decide to visit the amusement park on any given day, the probability that all 6.7 million will decide to visit on the same day is:

`P(All) = ((1)/(5,000))^(6,700,000)\\P(All) \ $\approx$ 0`

The probability is very close to zero. It is not exactly zero since there still is a very slim chance.
