Does it pay to ask for a raise? A national survey of heads of households showed the percentage of those who asked for a raise and the percentage who got one. According to the survey, of the women interviewed, 26% had asked for a raise, and of those women who had asked for a raise, 45% received the raise. If a woman is selected at random from the survey population of women, find the following probabilities. (Enter your answers to three decimal places.) (a) P(woman asked for a raise)(b) P(woman received raise, given she asked for one)(c) P(woman asked for raise and received raise)

Tay-Sachs disease is a genetic disorder that is usually fatal in young children. If both parents are carriers of the disease, the probability that each of their offspring will develop the disease is approximately 0.25. Suppose a husband and wife are both carriers of the disease and the wife is pregnant on four different occasions. If the occurrence of Tay-Sachs in any one offspring is independent of the occurrence in any other, what are the probabilities of these events? (Round your answers to five decimal places.) n USE SALT (a) all four children will develop Tay-Sachs disease (b) only one child will develop Tay-Sachs disease (c) the fourth child will develop Tay-Sachs disease, given that the first three did not
