The amount of time it takes Greg to drive the school bus route in the morning is given by the function t = 14 + 3x, where x is the number of stops he makes. Which is the best interpretation of this function? A. The amount of time it takes Greg to drive the route does not depend on the number of stops he makes.
B. The minimum amount of time that it takes Greg to drive the route is 3 minutes.
C. Each stop that Greg makes adds 14 minutes to the total time.
D. Each stop that Greg makes adds 3 minutes to the total time.

answer: 25 is the correct answer

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
