Question

Probability of drawing one yellow ball from a box containing 20 blue balls, 15 white balls and 10 yellow

​

Answer 1

`(2)/(9)`

Explanation:

The probability of an event is calculated by dividing the number of successful outcomes by the number of total outcomes. In an algebraic expression, that would be
`(successful)/(total)`.

In this case, there are a total of
`20+15+10=45` ways to choose any ball, since there are
`45` balls in the box. However, only
`10` are yellow, so there are
`10` ways to successfully choose a yellow ball. Therefore, the probability of choosing a yellow ball is
`(10)/(45)=(2)/(9)`. Hope this helps!
