The school chef put 3 apple pies, 2 blueberry pies, 4 peach pies, and 1 lemon pie in the oven to bake. At the start of lunch she randomly takes out one pie and does not put it back. 20 mins later she randomly selects another pie. What are the chances of her selecting a peach pie and then a lemon pie? Write your answer as a percent.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
