- The probability of Richard winning a prize in a game at the fair is 0.15
Richard plays a number of games.
- Find the probability of Richard winning his second prize on his 8th game,
- State two assumptions that have to be made, for the model used in part (a) to be valid.
M ary plays the same game, but has a different probability of winning a prize. She plays until she has won r prizes. The random variable \(G\) represents the total number of games M ary plays.
- Given that the mean and standard deviation of G are 18 and 6 respectively, determine whether Richard or Mary has the greater probability of winning a prize in a game.
