Ashley has 20 pieces of candy in a bag: 2 mint sticks, 4 jelly treats, and 14 fruit tart chews. If she eats one piece every 8 minutes, what is the probability her first two pieces will both be jelly treats?
The probability that her first treat is jelly is 4/20. Since she eats the candy and does not replace it, the probability the second treat is jelly would be 3/19 (1 less jelly and 1 less total candies). You would then multiply (4/20) by (3/19). That is your answer.
