Pablo makes a spinner to model the probability of simultaneously flipping a "heads" on a nickel, "heads" on a dime, and "heads" on a quater. He divides his spinner wheel into sections for each possible combination of coin flips, and he colors green the section representing simultaneously flipping three "heads". If he decides to spin the arrow on the spinner 24 times, how many times can he predict the arrow will land on the green section?​
