Solution

Let S be the sample space of drawing a card from a well-shuffled deck.

`n(S)=""^52C_1=52`

There are 4 king and 4 queen cards in a deck.

So there are 4 4 =8 cards which are either king or queen.

a card which is either a king or a queen can be drawn in ` ""^8C_1=8`

Probability of drawing a card which is either a king or a queen=8/52=2/13

  Is there an error in this question or solution?
