1. A statistical analysis of the wait time (in minutes) at the checkout line of a certain supermarket yields the probability distribution in the table.
Wait (in minutes) Probability
At most 3 0.1
More than 3 and at most 5 0.2
More than 5 and at most 10 0.26
More than 10 and at most 15 0.25
More than 15 0.19
