A shelf has 4 blue pairs of pants, 2 black pairs of pants, 1 white pair of pants, and 3 tan pairs of pants. You randomly choose a pair of pants from the shelf. What is the probability of choosing a pair of pants that is not white?

9/10 probability

Step-by-step explanation:

What you're trying to figure out is how likely the pants you select to not be white. The formula for this sort of thing is:

(How many things fit the probability you're looking for)/(However may there are of the thing total)

Because 9 of the clothes are not white, and would therefore fit the probability you're looking for, you would put 9 at the top (4 blue, 2 black, 3 tan)

Lastly, add all the clothes up total and put that number on the bottom (4 + 2 + 1 + 3 = 10)

Therefore, the answer is 9/10

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
