The data on the table represent the number of live multiple delivery births (three or more babies) in a particular year for women 15 to 54 years old. Use the data to determine the following. (Round all answers three decimals)

Determine the probability that a randomly selected multiple birth for women 15-54 years old involved a mother 30 to 39 years old. P(39 to 39) =

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) =

Determine the probability that a randomly selected multiple birth women 15-54 years old involved a mother who as less than 45 years old. P(less than 45)=
