Question: The graph of the discrete probability distribution below represents the number of live births by a mother 50-54 years old who had a live birth

The graph of the discrete probability distribution below represents the number of live births by a mother 50-54 years old who had a live birth in 2013.

(a) What is the probability that a randomly selected 50- to 54-year-old mother who had a live birth in 2013 has had her fourth live birth?
(b) What is the probability that a randomly selected 50- to 54-year-old mother who had a live birth in 2013 has had her fourth or fifth live birth?
(c) What is the probability that a randomly selected 50- to 54-year-old mother who had a live birth in 2013 has had her sixth or more live birth?
(d) If a 50- to 54-year-old mother who had a live birth in 2013 is randomly selected, how many live births would you expect the mother to have had?

Number of Live Births, 50- to 54-Year-Old Mother 0.4 0.352 0.35 0.3 0.262 0.25 0.2 0.15 0.124 0.096 0.1 0.047 0.054 0.05 0.018 0.020 0.016 0.011 0+ 4 5 9. 10 Child Number Probability 2.
