There are four pens on a table: red, blue, green, and black. If I take a random pen, what's the probability that it'll be a green one?

Answers

The number of the favorable outcome is 1 (green pen). The number of the all possible outcomes is 4 (red, blue, green, black). The required probability is equal to 1/4 = 0.25.
