104°

This is because there are two lines, each line is 180°, so both is equal to 360°. Angle y and the one with 76° are the same, so that should mean angle z and x are the same. So you subtract 152° from 360° (76° doubled) and you get 208° leftover. Now to get the last two angles, you divide 208° by 2, so each angle should be 104°. :))

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

6e14 is the answer.
