This triangle has an exterior angle labeled la. all of the interior angles are labeled correctly.
z60°
which statement about the exterior angle is correct?
it is 140° because it is supplementary to 40°.
it is 50° because it is complementary to 40°.
it is 60° because 60° +40° = 100°.
it is 120° because 40° +80° - 120°.

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

care to share were the trapezoid shown is ?

hm let me think hm think think hm think yes
