Gaydar Exercise 10 in Chapter 1 describes a study thatshowed that heterosexual women, during ovulation, weresignificantly better at correctly identifying the sexualorientation of a man from a photograph of his face than women who were not ovulating.

If this is theprobability of correctly identifying the orientation of aman in any given photograph, what is the probability awoman would correctly classify 80 or more of the men(as two women in the study did)?
