A box contains 3 plain pencils and 3 pens. A second box contains 7 color pencils and 5 crayons. One item from each box is chosen
at random. What is the probability that a plain pencil from the first box and a color pencil from the second box are selected? Write your answer as a fraction in simplest form.
The lowest common denominator of the two fractions is 4 because it is the smallest number that both fractions can be transformed into. 3/2 is multiplied by 2 to create 6/4 which can be added to 11/4.
