If two orders are selected, find the probability that they are both from Restaurant D.
a. Assume that the selections are made with replacement. Are the events independent?
b. Assume that the selections are made without replacement. Are the events independent?

a. Assume that the selections are made with replacement. Are the events independent?
The probability of getting two orders from Restaurant D is 1. The events
independent because choosing the first order
V the probability of
the choice of the second order.
