Explanation:
So in the case of Jillian, landing the beanbag in the cornhole is 1/2. So this is just like flipping a coin.
the first time she tosses the beanbag she has a 1/2 chance of getting it in the cornhole and 1/2 chance of getting it outside the cornhole. And since she needs to get 5 tosses in a row into the cornhole, we multiply
1/2(1/2)(1/2)(1/2)(1/2)=1/32
I hope that helps :)
