Question

For the high jump in a school competition, each competitor receives multiple opportunities to clear the bar at each height. On average, Shane completes 2 out of 3 jumps on the lowest bar, 4 out of 6 jumps on the middle bar, and 1 out of 4 jumps on the highest bar.

Write an equation that you could use to find Shane’s overall average number of jumps completed.

Answer 1

Answer:

Average number of jumps on lowest bar = 3/2 = 1.5

Average number of jumps on middle bar = 6/4 = 1.5

Average number of jumps on highest bar = 4/1 = 4

Overall average number of jumps = 3/2 + 6/4 + 4/1 = 7

Overall average number of jumps = 1/probability of complete the lowest bar +1/probability of complete the middle bar + 1/probability of complete the highest bar

Equations of Shane’s overall average number of jumps completed = x * (7/13), where x is the total number of overall jumps
