Probability

In a game at a fraternity party, there are 10 bottles to knock down. Five fraternity brothers line up to shoot the bottles down, each a perfect shot. Each brother selects one bottle at random and shoots. Find the e-value of your distribution of the number of bottles knocked down.

Each brother is a perfect shot so the probability of a brother knocking down their bottle = 1.

The brothers select a bottle at random so more than one brother can target the same bottle.
