In a randomized experiment involving a new vitamin supplement intended to reduce the chances of catching a cold, suppose that subjects were randomly divided into two groups of 100 each. Over the course of an entire winter, 13 of the subjects receiving the supplement got colds and 24 of ...

5.5 ROBABILITY AS A THEORETICAL CONCEPT Equally Likely
... This process can be extended. For example, for a three-child family, as we considered in Section 5.2, the number of possible family combinations is found as shown in Figure 5.5. You can see that a tree diagram is not required to carry out the counting process, but it is a very helpful tool. We can u ...
