A binomial distribution can only be used when there are 2 possible outcomes, no more, no less.
Looking at the situations given you are able to use a binomial distribution in 2 cases.
First is the quarter being flipped 3 times. There are only two possibilities (Heads or Tails).
Second is the 3 marbles being pulled out of the bag. There are only two types of marbles (Green and Blue).
80% of x = 32
80% × x = 32
.80x = 32
x = 32/.80
x = 40
80% of 40 games is 32 games.
