Answer
No. of possible outcomes = 52.
(i) There is one king of hearts and one king of diamonds in a deck.
No. of favourable outcomes (of getting a king of red colour) = 2
P(drawing a king of red colour)
= .
Hence, the probability of drawing a king of red colour = .
(ii) There are 12 face cards (3 of each suit) in a deck.
No. of favourable outcomes (for getting a face card) = 12
P(drawing a face card)
= .
Hence, the probability of drawing a face card = .
(iii) There are 6 red face cards (3 of hearts and 3 of diamonds) in a deck.
No. of favourable outcomes (for getting a red face card) = 6
P(drawing a red face card)
= .
Hence, the probability of drawing a red face card = .
(iv) There is one jack of hearts.
No. of favourable outcomes (for getting a jack of hearts) = 1
P(drawing a jack of hearts)
= .
Hence, the probability of drawing a jack of hearts = .
(v) There are 13 spade cards in a deck.
No. of favourable outcomes(for getting a spade) = 13
P(drawing a spade)
= .
Hence, the probability of drawing a spade = .
(vi) There is 1 queen of diamonds in a deck.
No. of favourable outcomes(for getting queen of diamonds) = 1
P(drawing a queen of diamonds)
= .
Hence, the probability of drawing a queen of diamonds = .
