Line up the binomials (or any polynomials) as you would for multiplying large numerical values. Following the pattern of number multiplication, start with the right-hand term of the bottom binomial (+4). Multiply this value times both terms of the top binomial. Now move to the left-hand term of the bottom binomial (x).
The probability of drawing a purple piece during the first class is 7/25 because 7 pieces of paper are purple out of a total of 25 pieces of paper
Since all pieces of paper are returned, the probability of drawing a blue piece during the second class is 2/25 since there are 2 blue pieces out of a total of 25 pieces of paper
The wording is meant to trick you here. If the purple paper from the morning was not replaced before drawing the probability of drawing a blue piece in the second class would increase.
Always remember to reduce fractions where you can
