A triangle has side lengths of (6.7u−8.7v)(6.7u−8.7v) centimeters, (9.1u−5.5w)(9.1u−5.5w) centimeters, and (6.6w+1.8v)
Which expression represents the perimeter, in centimeters, of the triangle?
A-15.8u-3.7w-2.1v
b-1.1w-6.9v+15.8u
c-3.6uw+8.4vw-2uv
D-22.4 uw-12.4vw

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

x = 3 ± √(5+y)
