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.

Answer 1

First box contains 5 plain pencils and 5 pens. If one item is picked at random, what is the probability that it is a plain pencil?

Answer 8

Probability of an event happening =
Number of ways the event can happen / Total number of outcomes

First box contains 5 plain pencils and 5 pens. If one item is picked at random, what is the probability that it is a plain pencil? There are a total of 10 items. 5 of them are plain pencils. Therefore, Number of ways the event can happen = 5 and Total number of outcomes = 10
Probability of a plain pencil = 5/10 = 1/2

Similarly, probability of picking a color pencil from the second box =
Number of color pencils / Total number of items in the second box = 5/8

The combined probability is: 1/2 * 5/8 = 5/16
