Select all the expressions that could represent the volume of a box, which is a fourth degree polynomial in variables x and y.
A. 3x2y2 + 6x2 – 7xy – 14x
B. 10xy + 12x + 2xy2 – y2 – 5y – 6
C. –6 + 7xy + 9x2 + 2x3y
D. 2x3y + 5x2y – xy – 6y
E. 3x4y4 – 3x2y + 17xy2 – 10y

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
