The senior classes at High School A and High School B planned separate trips to New York City. The senior class at High School A rented and filled 6 vans and 14 buses with 516 students. High School B rented and filled 8 vans and 7 buses with 338 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.

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

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
