Answer:

3/15 x 12/14 = 36/210 = 6/35

Step-by-step explanation:

3 + 12 = 15

3/15 = black

12/15 = green

the probability Lila selects the black ribbon first is 12/15

Lila has taken one away so the total now decreases by one to 14

There are 3/14 black ribbons now, and hence the probability that Jessica takes one is 3/14.

Then you just multiply the two together:

3/15 x 12/14 = 36/210 = 6/35

So as a result, The simplified answer is 6/35
