Children under 10 years and older people over 65 years receive a discount on movie tickets. let x represent the age of a person who receives a discount. which inequality represents the age of a child who receives a discount? which inequality represents the age of an older person who receives a discount? which compound inequality represents the age of a person who receives a discount?

0<x<10

x>65

0<x<10 or x>65

how am i supposed to answer

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
