Suppose the average wait at IHOP is 6 minutes
A. Find the probability that you will be called in the first 2 minutes of your wait
B. Find the probability that your wait will be greater than 6 minutes
Explanation / Answer
The average wait time is 6 minutes;
A) There is no mention of the standard deviation of the wiat time, or if it follows normal distribution, or the length of the queue, so it is difficult to estiamte the probability of being called in the first 2 minutes of waiting. However, it can be safely said that it is substantially less than 1/2, as 2 minutes is much lower than the average 6 minutes;
B) The probability of waiting greater than 6 minutes is as much as the probability of waiting less than 6 minutes, since 6 minutes is the average time. Thus, probability of waiting for greater than 6 minutes = 1/2;
