# A box is filled with 6 brown cards, 6 yellow cards, and 2 blue cards. A card is chosen at random from the box. What is the probability that it is a brown or a blue card?

$P \left(\text{randomly choose a brown or blue card}\right) = \frac{8}{14} = \frac{4}{7}$

#### Explanation:

There are 14 cards in total and 8 of them are either brown or blue. That gives:

$P \left(\text{randomly choose a brown or blue card}\right) = \frac{8}{14} = \frac{4}{7}$
