Question

the percent distribution of the multiple - delivery births (three or more babies) by a particular year for women 15 to 54 years old is shown in the pie chart. find each probability. write your answer as a decimal rounded to 3 places.

number of multiple births

15 - 19 1.4%
20 - 24 6.1%
25 - 29 21.7%
30 - 34 37.3%
35 - 39 24.7%
40 - 44 5.2%
45 - 54 3.6%

p(30 to 39) =
p(15 to 39) =
p(more than 40) =
p(less than 25) =

Explanation:

Answer:

(1) \(P(30 - 39)=0.373 + 0.247 = 0.62\)
(2) \(P(15 - 39)=0.014+0.061 + 0.217+0.373 + 0.247 = 0.912\)
(3) \(P(\text{more than }40)=0.052 + 0.036=0.088\)
(4) \(P(\text{less than }20)=0.014\)
