Help me out a bit, dont know how to

[stokken]

Say I am in the SB and hold A9os.

There are then 3 A`s left and 4 ranks higher then my 9

There are 3 ways to be delt AA, and twelwe ways of Ax x= T-K

So so 51 combinations of A and the higer ranked cards?

There are 52x51/2= combinations of any two cards, but I hold 2 so 50x49/2= is the number that I will compare my feared combinations towards?

What then if I am on co adding 3 players to the situation.
Likelyhood of any of the combinations I fear then? Simply add? What about if there are more then one Ax hand there?

Please help, new to this
