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!

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!

:P

(Can someone double check? Thanks)

4th  one.....here's what I get.......

Anchor  a boy in any position

If  no  boy  can be  next to another,  they  must alternate  B - G - B - G    etc.

So.....the  number of arrangements  =   10! * 9 !
