Find P(18-34).

QUESTION 11

What is the probability that a randomly selected individual does not have health insurance coverage?

QUESTION 12

What is the probability that someone between 18 and 34 years does not have health insurance?

QUESTION 13

If the individual is age 35 or older what is the probability that the individual does not have health insurance coverage?

QUESTION 14

Given the individual does not have health insurance, what is the probability that the individual is in the 18-34 group?

QUESTION 15

What is the probability that some older than 35 has health insurance?

Solution:

( 11 )

probability that a randomly selected individual does not have health insurance coverage = 300 / 2000 = 0.15

( 12 )

probability that someone between 18 and 34 years does not have health insurance = 170 / 920 = 0.1847

( 13 )

probability that someone over 35 years does not have health insurance = 130/1080 = 0.1203

( 14 )

probability that the individual is in the 18-34 group, Given the individual does not have health insurance = 170 / 300

= 0.5666

( 15 )

the probability that some older than 35 has health insurance = 950 / 1080 = 0.8796

Yes no total 18 - 34 750 170 920 35+ 950 130 1080 total 1700 300 2000
