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

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
