Marilyn has 10 caramels, 12 mints, and 14 bars of dark chocolate in a bag
Total = 10 + 12 + 14 = 36

1st pick a mint: 12/36 = 1/3
2nd pick a mint: 11/35
3rd pick dark chocolate: 14/34 = 7/17

The exact probability that Marilyn picks a mint, then another mint, and finally a bar of dark chocolate is:

1/3 x 11/35 x 7/17 = 77 / 1785 = 11/255

Answer
11/255
