B

Step-by-step explanation:

Step 1: First check the variables in the question

If we look at the equation we are trying to match it has a -3x and a 4y

Step 2: Look at the variables in the answers

If we look at the variables in the question we first can simplify the variables(Collect like variables).

Step 3: Compare the variables

If we look at the variables the only answer that doesn't have the correct variables is option B

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
