Suppose that f (t) = 0.3e^(−0.3t) is the probability distribution
function for the wait time T that a spider must wait to capture
prey where 0 ≤ t and t is in days.
• Make a sketch depicting the probability that a spider waits
between 2 and 5 days.
• Compute the value of the probability in the previous part.
• What is the probability that a spider must wait more than
7 days to capture prey?
