Pivot Table Question - Finding Percentages of Counts

Hello,

After using Excel for years (still quite a novice), I have just discovered Pivot Tables. I love them!

Here's my fun scenario. I have 5 game show participants, and I will throw varying amounts of dollar bills at them throughout the day. Some will not be able to play for the entire day, and some will be motivated to play if there's lot of $$$ to be had. I have made a Pivot and I can see how much money was in play for that hour. I can't seem to figure out how I can determine based on the total number of times I thew money out, the % of times each player caught the money. So basically I want % distribution of total attempts during a specific hour. If at 4 AM, I threw money out 5 times, "Frank" won twice, "Greg" once, "Moe" once, and "Tom" once, I would want to see a 40%, 20%, 20%, 20%, and 20% in my Count column. I've tried a few different options in the Pivot Table but hasn't yielded results I'm looking for.

I attached a quick sample sheet.
