The data on the right represent the number of live multiple-delivery births (three or more babies) in a particular year for Number of Multiple women 15 to 54 years old. Use the data to complete parts (a) through (d) below. Age Births 15-19 20-24 510 25-29 1637 30-34 2822 35-39 1850 40-44 377 45-54 116 . . .. . (a) Determine the probability that a randomly selected multiple birth for women 15-54 years old involved a mother 30 to 39 years old. P(30 to 39) = (Type an integer or decimal rounded to three decimal places as needed.) (b) Determine the probability that a randomly selected multiple birth for women 15-54 years old involved a mother who was not 30 to 39 years old. P(not 30 to 39) = (Type an integer or decimal rounded to three decimal places as needed.) (c) Determine the probability that a randomly selected multiple birth for women 15-54 years old involved a mother who was less than 45 years old. P(less than 45) =
