I would like to know how to get the probabilities p1, p2, p3 ... of two random variable in a table?
Attachment 23652
I just know that the sum of all probabilites p1, p2, p3... must be equal to 1!

Just let 
form a matrix )
where \cdot P(y_n))
.
Re: 2D table of random variables
Thank you, the sum is really 1. Can I ask is this a general rule? Is correlation or dependence effect this?
