Question

A bowl contains five red chips, seven blue chips, six yellow chips, and 10 green chips. one chip is randomly drawn. write the answer as a fraction in simplest form. find the probability of choosing a blue chip.

Answer 1

we are asked to determine the probability of getting a blue chip. To do that let's remember that the probability of a random variable is defined as the number of desired outcomes over the number of total outcomes. The number of desired outcomes is the number of blues chips and the number of all possible outcomes is the total number of chips.

The total number of chips is:

`\begin{gathered} N=5+7+6+10 \\ N=28 \end{gathered}`

The number of blue chips is 7, therefore, the probability is:

`P=(7)/(28)`

Simplifying:

`P=(1)/(4)`
