Question

A box is filled with 9 yellow cards, 5 red cards, and 6 blue cards. A card is chosen at random from the box. What is the probability that it is a yellow or a blue card? Write your answer as a fraction in simplest form

Answer 1

`(3)/(4)`

Explanation:

There are 20 total cards ( 9 + 5 + 6). 15 of them are yellow or blue(9 + 6). So, the fraction is
`(15)/(20)`.
`(15)/(20)` simplifies to
`(3)/(4)`.

Answer 2

`(3)/(4)`

Explanation:

9 + 5 + 6 = 20 (how many cards there are altogether)

9 yellow + 6 blue = 15 (how many cards are either yellow or blue)

so:

`(15)/(20)`

simplified:

`(3)/(4)`
