Answer 1

1/110

Explanation:

These are DEPENDENT events.

In the bag:

3 Hersheys

2 Reeses

5 York

1 Jolly Rancher

_______

11 total pieces.

For the first selection, there are 2 Reeses out of 11 pieces so the prob(Reeses) = 2/11

She eats it (so it's not going back into the bag).

Now here's what's left in the bag:

3 Hersheys

1 Reeses

5 York

1 Jolly Rancher

_______

10 total pieces.

The probability of selecting a reese's this time is 1/10.

Multiply those 2 together for the answer:

(1/11) * (1/10) = 1/110
