The time, T (measured in seconds), between successive hits on a website (“inter-hit time” in the rest of the problem) follows the exponential distribution with parameter 1/2. (a) What is the probability that a randomly selected inter-hit time is between 1 and 3 seconds? (b) Assume that different inter-hit times are independent of each other. A random sample of 810 inter-hit times is obtained. Give an exact symbolic expression for the probability that more than 290 of the inter-hit times in the sample are between 1 and 3 seconds? (c) Obtain a good numerical approximation for the probability from part (b)
