Textbook Question
Chapter 16.3, Problem 11P
There are 3 plastic bears in a bag. The teacher tells Bob that there are 3 bears in the bag, but she doesn’t tell him what color the bears are. Bob picked a bear out of the bag 3 times and each time he got a red bear. (He puts the bear he picked back in the bag before picking the next bear).
a. Bob says that the 3 bears in the bag must all be red. Is he necessarily correct?
b. Now suppose that of the 3 bears in the bag, 2 are red and 1 is blue. Calculate the probability of picking 3 red bears in 3 picks.
