I had a test today. Heres one of my questions. Can someone do it, because im not sure if I got it right, and I'd like to know now.

You have two different dice. One die has a 1 and five 3's.
The next die has four 2's and two 6's.

Like this:

Die 1- 133333
Die 2- 222266

Set up this table:
X __ __ __ __
p(X) __ __ __ __

What is the mean?
What is the standard deviation?

For the X's, I put 3, 5, 7, 9
Can someone do this so I can see if im right with everything? I'd really appreciate it! thanks

2. I am sorry but I am in a great hurry.
So here is a brief help. There are still 36 elementary events.
3 gotten in 4 ways
5 gotten in 20 ways
7 gotten in 2 ways
9 gotten in 10 ways
