Do both parts of problem 2 if 4 cards are drawn at random.

Text Solution

Verified by Experts

4 cards are drawn one after another. As they are of different suits, we have their probability
`=52/52xx39/51xx26/50xx13/49`
As the cards are of different denominations,we have their probability `= 52/52xx48/51xx44/50xx40/49`
