At a track meet 2/5 of the first place finishers went to Ohio State. One half of Ohio State's first place finishers were women. If 2/9 of the first place finishers who did NOT attend Ohio State were women, what fractional part of the total number of first place finishers were men?
Homework Answers
P(female) =P(went to Ohio)*P(female|went to Ohio)+P(not went to Ohio)*P(female|not went to Ohio)
=(2/5)*(1/2)+(1-2/5)*(2/9) =1/3
therefore P(male) =1-P(female) =1-1/3 =2/3

Here we examine data from sixteen student volunteers at Ohio State University who each drank a randomly assigned number of cans of beer. These students were evenly divided between men and women, and they differed in weight and drinking habits. Thirty minutes later, a police officer measured...

(The following passage is excerpted from a magazine article first published in 1981.) A few weeks before my twenty-fifth reunion last spring, a Washington reporter called to say she was writing an article on why so many women of accomplishment had gone to Smith College. "Don't you think it's remarkable that the two top women in the country went to the same college?" "Like who?" I asked cautiously, sensing a news peg. "Like Nancy Reagan and Barbara Bush,"[2] she said....
