Answer:
0.01265
Step-by-step explanation:
Since, if the time to be served has an exponential distribution with a mean of 7, then
Chance to be served in under 2 minutes:
Let A represents the number of days when a person is served in less than 2 minutes,
Hence,
the probability that a person is served in less than 2 minutes on at least 5 of the next 7 days ( using binomial distribution )
= P(A=5) + P(A=6) + P(A=7)
≈ 0.01265
I decided to do mental math and figured out it was -12. but you can cross multiply since both answers have to equal one another. you will still get the answer.
