<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>
