Given the probabilities listed above, we are asked for the following:
P(Favorite activity is swimming if a girl)
P(Favorite activity is reading if a boy)
P(Favorite activity is swimming if a boy)
P(Favorite activity is reading if a girl)
So,
P(Favorite activity is swimming if a girl) = 1 - 0.47 = 0.53
P(Favorite activity is reading if a boy) = 1 - 0.67 = 0.33
P(Favorite activity is swimming if a boy) = 0.47
P(Favorite activity is reading if a girl) = 0.67
