## Help please

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
