There are eight boxes. each box holds one sweater. there are 3 blue, 2 brown, 1 green, and 2 red sweaters. what is the probability of first selecting a brown sweater and then a green sweater?

a) 1/28

b) 3/56

c) 3/15

d) 1

3 + 2 + 1 + 2 = 8, which is the amount of sweaters.
The probability of a brown sweater is 2 / 8 = 0.25
And the probability of a green sweater is 1 / 8 = 0.125.

Multiply the two probabilities together to get the probability of choosing brown then green:
0.25 * 0.125 = 0.03125.

To convert a decimal to fraction, you multiply the numerator and denominator, or in this case  by 1000 which gets 

Which can be simplified to:
.

Hope this helps.
