Question

As shown above, a classic deck of cards is made up of 52 cards, 26 are black, 26 are red. Each color is split into two suits of 13 cards each (clubs and spades are black and hearts and diamonds are red). Each suit is split into 13 individual cards (Ace, 2-10, Jack, Queen, and King).

If you select a card at random, what is the probability of getting: (Round to 4 decimal places where possible)

a) A 9 of Diamonds?

b) A Club or Spade?

c) A number smaller than 3 (counting the ace as a 1)?

Answer 1

a).probability of getting a 9 of diamonds be:-

[ there are 1 card which is 9 of diamond]

b). probability of getting a club or spade be:-

[ number of spade = number of club =13 ]

c).probability of getting a number smaller than 3 be:-

[ in each suits, number of card smaller than 3 = 2( ace, 2 )

so, total number of card smaller than 3 in a deck = (4*2) = 8 ]
