Final answer:
The given statement, " each player shall serve for a total of five points just for their team" is false.
Step-by-step explanation:
No, it is not more likely that four or five seniors participated in after-school sports all four years of high school based on numerical values. To justify this, let's assume that the probability of a senior participating in after-school sports is p. If the probability is the same for each year, then the probability of one senior participating in all four years is p^4.
Therefore, the likelihood of four or five seniors participating in after-school sports all four years of high school is less than the likelihood of just one senior participating in all four years.
