How are the semicircle and the diameter of a circle related?

A. The length of the diameter and the length of semicircle are the same.
B. The degree measure of the diameter and the degree measure of the semicircle are the same.
C. The angle measure of the diameter is twice the angle measure of the semicircle.
D. The angle measure of the diameter is half the angle measure of the semicircle.

B. The degree measure of the diameter and the degree measure of the semicircle are the same

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

answer is because 4×10=40

and 98×4= is 392
