Chords SK and QI intersect to form 21. Chord SK intersects tangent No to form 22. Find m1 and m2. If necessary, round to the tenths place.
A. mZ1 = 3°
m2 = 56.5°
B. m2 = 110°
m2 = 102°
C. m1 = 110°
m2 = 113°
D. m2 = 220°
m2 = 204°

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

your answer is  

a.
