Amy and Natalie each improved their yards by planting grass sod and ivy. They bought their supplies from the same store. Amy spent $137 on 11 ft^2 of grass sod and 6 pots of ivy. Natalie spent $190 on 10 ft^2 of grass sod and 12 pots of ivy. Find the code of one ft^2 of grass sod and the cost of one pot of ivy.

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
