Answer:

3 / 1352 ; 1 / 442

Explanation:

Since it isn't stated if selection is done with replacement or not, we calculate the probability for the two scenarios :

Number of diamond face cards in a deck = 3

Number of black 2's in a deck = 2

Total number of catds in a deck = 52

Assume selection is done with replacement :

1st draw :

P(diamond face card) = 3 / 52 =

2nd draw :

P(black 2's) = 2 /52

P(1st draw) * P(2nd draw)

3/52 * 2 /52 = 6 / 2704 = 3 / 1352

Drawing without replacement :

P(diamond face card) = 3 / 52 =

2nd draw :

P(black 2's) = 2 /51

P(1st draw) * P(2nd draw)

3/52 * 2 /51 = 6 / 2652 = 1 / 442
