In an open refrigerator there are seven different
types of diet soda four different types of regular soda and two types
of bottles of water. a. Suppose Evan chose a bottle from the
refrigerator at random. Could we realistically say that the probability
of choosing a diet soda is 7/13? Why or why not? b. If there are 16
total bottles of diet soda 8 total bottles of regular soda and 4 total
bottles of water what is the probability of each of the following: (i)
Choosing a bottle of diet soda when a bottle is chosen at random (ii)
Choosing a bottle of regular soda when a bottle is chosen at random
(iii) Choosing a bottle of water when a bottle is chosen at random
