The probability of getting 3 diamonds = 13C3. The Probability of getting 1 spade = 13C1 And total outcome = 52C4 So probability of getting 3 diamonds and 1 spade = (13C3 * 13C1)/52C4. final answer will be 858/62475..

Teaching because it is fun

4 cards from a pack of 52 can be drawn in 52C4 ways 3 Diamonds can be drawn from the available 13 Diamonds in 13C3 ways, and 1 Spade can be drawn from the available 13 Spades in 13C1 ways. Therefore, the answer is, (13C3 X 13C1) / 52C4

A Clock strikes three ( at 3 AM ). And when it does so 3 seconds elapse. How long does it take the clock to strike seven ( at 7 AM )?
Between the three strikes there are 2 intervals, which are each 1.5 seconds long. To strike seven there are 6 intervals. So it will take total 6*1.5 = 9 seconds for seven strikes.
