### 8.2 Estimating Likelihood

• Math Help

The graph shows the number of combinations assigned to each of the 14 teams in the NBA Draft Lottery. In Example 2, you determined the probability that the team with the worst record wins the first pick is 25%. The graph supports this conclusion because the height of the bar for the team with the worst record is greater than the heights of all the other bars.

Is it more likely that the team with the worst record will not win the first pick? Using the graph, imagine stacking all of the bars for the other 13 teams, as shown in the figure below. The height of this stack is greater than the height of the bar for the worst team. So, it is more likely that the team with the worst record will not win the first pick.
