this should be right.
1,712,304 / 44 = 38,916 this means that in every 38,916 times the cards are dealt, quads will occur only once.
so you play 243 hands. this number will be divided - 38916/243 = 160ish.
so in 243 hand there is a 1 in 160 chance you will make quads.the odds of making this three times will simply be 160 x 160 x 160 = 1 in 4.1 million.
wow, thats steep if ive done it right.
