61.Previously, De Anza statistics students estimated thatthe amount of change daytime statistics students carryis exponentially distributed with amean of $0.88. Suppose thatwe randomly pick 25 daytime statistics students.

e. Find the probability that an individual had between $0.80 and $1.00.

Thank you!
