Timothy has 15 letters and 32 memos to type for his manager. He estimates that
each letter will take 40 minutes to type
and each memo will take 15 minutes to
type. He gets paid $5 a letter and $2 a
memo. If he works for a maximum of 5
hours (300 minutes), how many letters
and memos should Timothy type in
order to maximize his wages?

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
