Question

A drawer contains 8 red shirts, 6 blue shirts, and 7 white shirts. If a shirt is drawn at random, what is the probability that the shirt will be blue?

Answer 1

8 red, 6 blue, 7 white......total of 21 shirts

probability shirt will be blue is 6/21 which reduces to 2/7

Answer 2

The Probability of drawing shirt is blue is
`(2)/(7)`

Explanation:

Given : A drawer contains 8 red shirts, 6 blue shirts, and 7 white shirts.

We have to find the probability if a shirt is drawn at random, then the shirt will be blue.

Total number of shirt in drawer = 8 + 6 + 7 = 21

Number of blue shirts = 6

Probability of an event =
`\frac{\text{number of possible outcomes}}{\text{number of total outcomes}}`

Event (E) : shirt drawn is blue.

number of possible outcomes = 6

number of total outcomes = 21

Thus, the Probability of drawing shirt is blue is
`(6)/(21)`

Simplifying , we get,

The Probability of drawing shirt is blue is
`(2)/(7)`
