For the high jump, each competitor receives multiple opportunities to clear the bar at each height. On average, Shane completes 2 out of the 3 on the lowest bar, 4 out of 6 on the middle bar, and 1 out of four on the highest bar. write an equation that you could use to find Shane’s overall average number of jumps completed. Calculate Shanes average using the equation. I don’t just want the answer but I need someone to explain how to get the answer.
