probability 1st card is a diamond.....13 diamonds in the deck....13/52 reduces to 1/4
replace
probability 2nd card will be black....there are 26 black cards.....26/52 reduces to 1/2
replace
probability 3rd card is an ace....4 aces in the deck...4/52 reduces to 1/13
probability for all of that happening : 1/4 * 1/2 * 1/13 = 1/104 or 0.0096 or 0.96%
