D) 35 yards for $90.

Step-by-step explanation:

We have been given four options and we are asked to choose the option that represents the best deal.

Let us find the cost of per yard cloth for our given choices.

A.

Therefore, option A offers $4 per yard of cloth.

B.  

Therefore, option B offers $3 per yard of cloth.

C.  

Therefore, option C offers $2.75 per yard of cloth.

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
