Question 1142269: A box contains 4 plain pencils and 4 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 plan pencil from the first box and a color pencil from the second box are selected? Answer by ikleyn(52925) (Show Source):
The probability that a plain pencil from the first box is selected is = = .
The probability that a color pencil from the second box is selected is = .
These two events are independent (OBVIOUSLY); therefore, the final probability under the question
is the product of these partial probabilities
P(that a plan pencil from the first box and a color pencil from the second box are selected) = = . ANSWER
