Question

A certain region has a population of 5.55.5 million. On any given day, the probability is StartFraction 1 Over 5000 EndFraction15000 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? a. Choose the correct probability. A. Very close to one B. Exactly equal to one C. A very large number D. Very close to zero E. Exactly equal to zero

Explanation / Answer

a) Since the population is 5.5 million and probability of a randomly selected person to visit park = 1/5000 = 0.0002

Hence,

P(All 5.5 million people will decide to go tomorrow) is almost equal to zero.

Hence,

Option D is correct.

b) We have assumed that the probability is same for all residents and the decision of every resident is independent of others.
