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
Answer:
684
Step-by-step explanation:
Just divide, 8208/12
because 8208 is the number of tickets overall and 12 is how many performances
