(Type an integer or a decimal.) (b) What is the probability that a randomly selected 51- to 56-year-old mother who had a live birth in 2015 has had her fourth or fifth live birth in that year? (Type an integer or a decimal.) (c) What is the probability that a randomly selected 51- to 56-year-old mother who had a live birth in 2015 has had her sixth or more live birth in that year? (Type an integer or a decimal.) (d) If a 51- to 56-year-old mother who had a live birth in 2015 is randomly selected; how many live births would you expect the mother to have had?
