# Question: The following data represent the number of live multiple delivery births

The following data represent the number of live multiple-delivery births (three or more babies) in 2007 for women 15 to 54 years old:
Age ...... Number of Multiple Births
15–19 ...... 100
20–24 ...... 467
25–29 ...... 1620
30–34 ...... 2262
35–39 ...... 1545
40–44 ...... 328
45–54 ...... 105
Total ...... 6427
(a) Determine the probability that a randomly selected multiple birth in 2007 for women 15 to 54 years old involved a mother 30 to 39 years old. Interpret this probability.
(b) Determine the probability that a randomly selected multiple birth in 2007 for women 15 to 54 years old involved a mother who was not 30 to 39 years old. Interpret this probability.
(c) Determine the probability that a randomly selected multiple birth in 2007 for women 15 to 54 years old involved a mother who was less than 45 years old. Interpret this probability.
(d) Determine the probability that a randomly selected multiple birth in 2007 for women 15 to 54 years old involved a mother who was at least 20 years old. Interpret this probability.
