Suppose a basketball team had a season of games with the following characteristics:
Of all the games, 60% were at-home games. Denote this by H (the remaining were away games).
Of all the games, 25% were wins. Denote this by W (the remaining were losses).
Of all the games, 20% were at-home wins.
Of the at-home games, what proportion of games were wins? (Note: Some answers are rounded to two decimal places.)
A 0.12
B 0.15
C 0.20
D 0.33
E 0.42
Given, P(at-home games) = 0.60 ; P(wins) = 0.25 ; P(at-home games and wins) = 0.20
P(wins | at-home games) = P(at-home games and wins) / P(at-home games) ...........(conditional probability)
= 0.20 / 0.60
= 0.33
Therefore, of the at-home games, the proportion of games which were wins is 0.33
