Question

A box contains colored jelly beans. There are 14 red, 6 yellow, and x blue jelly beans in the bag. If the probability of drawing a yellow jelly beans is 1/4, what is the value of x?

Answer 1

36 blue jelly beans

Explanation:

We can find the total number of jelly beans by adding all red, yellow, and blue jelly beans together.

14+6+x

This simplifies to 20+x

For probability, it is (the number of things you want)/(the total number of things there are).

If the probably of drawing a yellow jelly bean is 1/4, we can set up this equation:

`(14)/(20+x)=(1)/(4)`

We can cross multiply:

`20+x=14(4)\\x+20+56\\x=36`

There are 36 blue jelly beans.

Answer 2

4

Explanation:

If the probability of drawing a yellow jelly beans is 1/4, the box is has 1/4 yellow jellybeans.

1/4b=6

b=24

14+6+x=24

20+x=24

x=4
