... 3. 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 w ...
