A survey of TV viewing habits of 50 men and 50 women found the following information: Of the 50 men, 20 prefer watching baseball and 30 prefer football. Of the 50 women, 25 prefer watching baseball and 25 prefer football. Construct a data table for this data and answer this question: Out of the entire survey, what is the probability of choosing a woman who prefers baseball?

Men Women Total
prefer
baseball 20 25 45
prefer
football 30 25 55
Total 50 50 100
P(pfW) = (25/100)/(50/100)
p = 25/50 = .5
