Problem 2

The following excerpt is from an MSNBC article on the prevalence of genital herpes in the population: “Despite the decline, blood tests of more than 11,000 people found 11 percent of men and 23 percent of women carry the genital herpes, or type 2, virus. Among people in their 20s, the infection rate was almost 11 percent.”  Use the information from the article to determine the probability that among 13 randomly selected women none of them are infected with genital herpes?
