Answer:

a. 0.158

b. 0.01942

Step-by-step explanation:

For part a we define probability that the randomly selected person is if 65 years or more than that

a.

Probability of under age = 22.8% = 0.228

Probability of those from age 18 to 64 = 61.4% = 0.614

1-0.228-0.614

= 0.158

b.

P(uninsured) = p(those not up to 18) * p(those uninsured or under 18) + p(those age 18-64) * p(uninsured or under 18) + p(being 64plus) x P(uninsured or 64 plus)

= 0.228 x 0.051 + 0.614 x 0.124 + 0.158 x 0.011

= 0.011628 + 0.076136 + 0.001738

=0.089502

P(65 of older|uninsured) = p(64+) x P(uninsured or 64 plus)

= 0.157 x 0.011/0.089502

= 0.001738/0.089502

= 0.01942
