There are 5 red roses, 3 yellow roses, and 8 white roses in a tray. If Stephanie picked 2 roses one after the other without replacing, then what is the probability of picking a white rose first and a red rose next?

So probility is (disired outcomes) divided by (total possible outcomes) so

1st one is white roses

8 white roses so 8 is disired

total=5+3+8=16

8/16=1/2

then without replacing them

red=5

total possible=16-1 since 1 picked

5/15=1/3

then multiply the probatilities

1/2 times 1/3=1/6

it is a 1 in 6 probability
