Step-by-step explanation:
25 times 7 =185
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
Final Answer: 2g + 1/18
3g - 1g - 1/9 + 1/6
2g - 1/9 + 1/6
- 1 × 2 -2
------- -------
9 × 2 18
+ 1 × 3 3
------- -------
6 × 3 18
