One card is drawn at random from a well-shuffled deck of 52 cards. Find the probability that the card drawn is (i) a king (ii) a spade (iii) a red queen (iv) a black 8.
(i) Total number cards in a deck = 52
Number of kings in a deck of cards = 4
Probability P() =
Probability of drawing a king from the deck of cards P(king)
= =
=
(ii) Total number cards in a deck = 52
Number of spades in a deck of cards = 13
Probability P() =
Probability of drawing a spade from the deck of cards P(spade)
= =
=
(iii) Total number cards in a deck = 52
Chances of drawing a Red queen from the deck of cards = 2 (they are queen of hearts and queen of diamonds)
Probability P() =
Probability of drawing a Red queen from the deck of cards P(Red queen)
= =
=
(iv) Total number cards in a deck = 52
Chances of drawing a black 8 from the deck of cards = 2 (they are 8 of clubs and 8 of spades)
Probability P() =
Probability of drawing a black 8 from a deck of cards P(black 8)
= =
