Question

Quizplus · Accepted Answer

When tossing a fair coin five times, all outcomes from 0 heads (all tails) to 5 heads (all heads) are possible, making the set {0,1,2,3,4,5} correct. However, these outcomes are not equally likely due to the different combinations that can result in each number of heads. For example, there is only 1 way to get 0 heads (all tails) and 1 way to get 5 heads (all heads), but there are more ways to get 2 or 3 heads, making some outcomes more likely than others.
