d. Suppose that waiting times on different mornings are independent. What is the probability that the waiting time is less than 5 minutes on exactly 4 of 10 mornings?

ANSWER:

Solution:

Step 1of 3:

The waiting time of a person in minutes, for a bus to arrive is uniformly distributed on the interval (0,15).

We have to find

  1. The mean of waiting time.
  2. The standard deviation of the waiting time.
  3. Probability that the waiting time is between 5 and 11 minutes.
  4. If the waiting times on different mornings are independent , what is the probability that the waiting time is less than 5 minutes on exactly 4 of 10 mornings.
