Each of four friends orders a sweatshirt from a catalog. there are 15 colors of sweatshirts, 5 of which are all cotton and 10 of which are a blend. each one orders a different color (no repeats) at random. what is the probability that the friends order only cotton sweatshirts?

Hence, the probability is:

Each of four friends orders a sweatshirt from a catalog.

There are 15 colors of sweatshirts, 5 of which are all cotton and 10 of which are a blend.

We have to find the probability that the friend order only cotton sweatshirt:

As there are 5 cotton shirts out of which four are to be selected from a total of 15 coloured shirts.

Now we know that a probability is defined as:

Probability=( Number of favourable outcomes)/(Total number of outcomes)/( Total number of outcomes)

So, the probability is:

Hence, the probability is:

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
