There are 25 motels. The number of rooms in each motel follows:
90 72 75 60 75 72 84 72 88 74 105 115 68 74 80 64 104 82 48 58 60 80 48 58 100
Suppose the last five motels are "cut-rate" motels. Describe how you would select a random sample of three regular motels and two cut-rate motels.
Three can be chosen from the first 20 motels in how many ways?
Two can be be chosen from the last 5 motels in how many ways?
