urther Practice Questions In a popular weekly number game, a computer generates a combination of 6 different numbers that can be any number from 1 to 15. A player places a stake for a choice of 6 different numbers from 1 to 15. He wins the game if he gets at least four of the numbers correct. Let X be the number of correct answers he has chosen. The distribution of X is illustrated in the table below. X P(X=x) 0 12 715 1 108 715 2 National Junior College 3 4 5 6 Copy and complete the probability distribution table of X. Hence find the probability of winning the game. Given that a player has won the game, what is the probability that he wins with five numbers?
