There are 6 blue socks, 7 white socks, and 8 gray socks in a drawer. If you pick sock without looking, what is the probability it will be blue?

Pr(blue) = 2/7

Step-by-step explanation:

Blue = 6

White = 7

Gray = 8

Total socks = 6+7+8 =21

Probability of picking blue = number of blue ➗ total number of socks

Pr(blue) = 6/21

Divide both by 3 to make the fraction to the lowest term.

Pr(blue) = 2/7

2/7

Step-by-step explanation:

6 blue socks

7 white socks and

8 gray socks

Total number of socks = 6 + 7 + 8

= 21

Probability of picking a blue sock without looking = no of blue socks / total number of socks

That’s 6/21

= 2/7

The probability of picking a blue sock is 2/7
