4 cards are drawn from a well shuffled deck of 52 cards. what is the probability of obtaining 3 diamonds and one spade ?
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..
