three friends Run a 10 mile relay each person runs an equal amount what fraction of the relay does each person run
Anon25 [30]

Hey there!

Since there are 3 friends running an equal amount of this relay race, each will run 1/3 of the relay.

This is because 3 thirds make a whole, and each third is equal to the others, so if you add each distance ran by each of the friends, or simply multiply each portion by 3, you'd get 10 miles.

If you're also looking for how long each friend runs, which I know isn't in the question but I'll add it anyways, it is 3 1/3 miles. This can be found by dividing 10 into 3 equal parts.

Hope this helps!

Each of four friends orders a sweatshirt from a catalog. There are 16 colors of sweatshirts, 7 of which are all cotton and 9 of
sashaice [31]
<span>There are 16 sweatshirts in total.
7 of which are cotton. 
There are 4 friends.
Say they all choose cotton sweatshirts,
First friend: (7/16)
Second friend: (6/15)
Third friend: (5/14)
Fourth friend: (4/13)

As you can see, there is a deduction in total number of sweatshirts available to be chosen and also in the total number of cotton sweatshirts available to be chosen.

Multiply these together = </span><span>(7/16)*(6/15)*(5/14)*(4/13)
= </span><span>0.01923076923 = 1.92%

1.92% is the probability all friends order cotton sweatshirts</span>
