Question

A box is filled with 9 brown cards, 2 yellow cards, and 3 blue cards. A card is chosen at random from the box. What is the probability that it is a brown or a blue

card?

Answer 1

9 / 14 for a brown , 3 / 14 for a blue

Explanation:

1) summarize all cards 9 (brown) + 2 (yellow) + 3 (blue)= 14 cards.

2) probability depends on how many cards of a particular color, how more cards, then more probability.

3) 9 brown cards, so probability = 9 brown cards to divide all cards 14.
