Question: Use the probability rules in this chapter to solve each of the following:

a. The probability that a randomly selected Caucasian American child will have blonde or red hair is 23%. The probability of having blonde hair is 14%. What is the probability of having red hair?

b. According to Blackenhorn (24-26 February 1995), in 1990 the probability that a randomly selected child was living with his or her mother as the sole parent was .216 and with his or her father as the sole parent was .031. What was the probability that a child was living with just one parent?

c. In 2001, the probability that a birth would result in twins was .0301, and the probability that a birth would result in triplets or more was .0019 (Source: National Center for Health Statistics.) What was the probability that a birth in 2001 resulted in a single child only?
