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
