Diet cola was on sale last week; it cost $10 for every 4 packs of cola. How much do 2 packs of cola cost?

I would say 5$

Step-by-step explanation:

You are going from 4 packs to 2 packs (so you are dividing by 2). So if you divide 10$ by 2 you get 5$

I hope this helps!

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
