Geraint is running a game in a school fair. A large number of balls are placed in a box. Each of the balls is one of three colours: bronze, silver or gold. In the game, a ball is chosen at random from the box. The table below shows the probability of choosing a bronze ball and the probability of choosing a silver ball.

In the game, each person pays £2 to choose a ball at random from the box. The ball is then returned to the box.

The person wins £3 if a silver ball is chosen. The person wins £8 if a gold ball is chosen. There is no prize for choosing a bronze ball.

100 people each play the game once.

How much profit would you expect Geraint to make?
