pre flop drawing odds

[2bithoe]

Im short stacked in a tournament with ace ten and blinding out. I push all in pre flop trying to steal the blinds knowing that if i get called my ten probably won't be good enough. How do you figure out what my odds of hitting another ace by the river? Is there an easy way? What about two cards like A,K or A,Q?

there r lots of books in the library on poker and all the odds in different situations your odds change with the amount of players alive at the table so i cant give u a number
