URGENT PLEASE HURRY Two classmates have decided to read all the volumes in a popular series of books. Katie has already read 10 volumes and will continue to read new ones at a rate of 2 volumes per week. Leah, who has not started reading the series yet, will read 3 volumes per week. At some point, Leah will catch up with Katie, and they will be reading the same book. How long will that take?

10 you would take 50/ .2

step-by-step explanation:

85.560%

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

just sum

10 + 10 = 20

answer: the answer is b. i think hope i got it correct
