60% of all basketball games were at home games. denotes this by H (the remaining were away games)

25% of the games were wins. denote this by W ( the remaining were losses)

20% of all games were at home wins

of the at home games, a class is interested in finding what proportions were wins.

To determine the % of the at home games that were wins. what needs to be determined first?

P(H/W)

P(H)

P(W/H)

P(W)

P(H and W)

P(H) = 0.60,
P(W) = 0.25
P(H n W) = 0.20

P(H/W) = P(H n W)/P(W) = 0.20/0.25 = 0.8

P(W/H)= P(H n W)/P(H) = 0.20/0.60 = 0.333
