If two orders areselected, find the probability that they are both from Restaurant D.

a. Assume that the selections are made with replacement. Are the eventsindependent?

b. Assume that the selections are made without replacement. Are the eventsindependent?

a. Assume that the selections are made with replacement. Are the eventsindependent?

The probability of getting two orders from Restaurant D is

nothing

. The events are

independent because choosing the first order does not affect

the probability of the choice of the second order.

(Do not round until the final answer. Round to four decimal places asneeded.)
