#1**+2 **

**Answer to #1: 2^95**

**Explanation:**

The person has 95 candies left. If he eats at least one per day, then he can the eating out for as long as 95 days (1 per day), or 1 day (95 per day).

Or in other words, 95 choose 1 + 95 choose 2 ... + 95 choose 95.

That sum is simply 2^n (a formula you should know for this), and n=95, so the answer is 2^95.

You are very welcome!

**Answer to #3: 1,260**

**Explanation:**

Since order doesn't matter, we can use the choose function.

2 are yellow, 3 are green, and 4 are blue.

\({9 \choose 2}=36\), since we are choosing 2 yellow out of 9 total.

Then \({7 \choose 3}=35\), 3 green out of 7 remaining.

4 out of 4 blue is 1.

36*35=1260.

You are very welcome!

(Can someone double check? Thanks)
