A box contains 4 plain pencils and 4 pens. A second box contains 5 color pencils and 3 crayons. One item from each box is chosen at random. What is the probability that a pen from the first box and a crayon from the second box are selected?

• First box, P(pen) = 4/8 = 1/2 = 0.5
• Second box, P(crayon) = 3/8

Since each event is independent, we have:
P(Pen from Box 1) * P(Crayon from Box 2) = 1/2 * 3/8 = 3/16 or 0.1875
