Suppose that the average time a fully charged6-volt laptop battery will operate a computer is 2 hours and follows the exponential probability distribution. Determine the following probabilities.

a) Determine the probability that the next charge will last less than 1.6 hours.

b) Determine the probability that the next charge will last between 2 and 3.4 hours.

c) Determine the probability that the next charge will last more than 5 hours.
