Answer:

Explanation:

Assume that after each shaking, a silver dollar has an equal chance of "head" or "tail" up.

There will be likely 100/2 = 50 dollar coins with "heads" up. Removing them leaves 50 coins.

Again after the second shakes, 50/2 = 25 coins will likely be "heads" up. Removing them leaves 25 coins.

After the third shakes, approximately 25/2 = 12.5 coins will be "heads" up. Of course there is no 0.5 coin. Rounding up you likely get to keep 13 dollar coins.
