Please explain the method


After the first draw, 51 cards left in the desk, of which 3 are aces. (Since first draw was an ace).

So probability of drawing an ace in the second draw = 3/51

Now, there are 50 cards left and 2 aces

So probability of drawing an ace in the third draw = 2/50

Hence probability of drawing 2 aces after the first one is an ace = 3/51 * 2/50 = 1/425
