Default Prob. of flopping one ace and one jack

Sklansky says in his no limit hold'em book on page 36 that the probablility of flopping exactly one jack and one ace are 0.1% when one player has a pair of jacks and the other a pair of aces.

I think it should be [2/48 * 2/47 * 44/46]=0.177%.

Default Re: Prob. of flopping one ace and one jack

It should be 2*2*44/48c3 =0.0101

That is , there are two aces and two jacks left and you must choose one of each and 44 non jack-ace cards .

or , 2/48*2/47*44/46*(3!)=0.0101 . You multiply by 3! because of the following reason .

Card 1 is an ace and card 2 is a jack and card three is x
card 1 is a jack and card 2 is an ace and card three is x.
card 1 is an ace and card 2 is x and card three is a jack
card 1 is a jack and card 2 is x and card three is an ace
card 1 is x and card 2 is an ace and card three is a jack
card 1 is an x and card 2 is a jack and card three is an ace

Also , your computations work out to 0.00169 which is 0.169%
