Answer:
The probability that the time between the next two calls is between 3 minutes and 7 minutes is 0.2442.
Step-by-step explanation:
Let <em>X</em> = time between calls made to Amazon's customer service.
The average time between calls is, <em>β</em> = 10 minutes.
The random variable <em>X</em> follows an Exponential distribution with parameter
The probability distribution function of <em>X</em> is:
Compute the probability that the time between the next two calls is between 3 minutes and 7 minutes as follows:
Thus, the probability that the time between the next two calls is between 3 minutes and 7 minutes is 0.2442.
