Question

when face card is drawn from a well shuffed deck of 52 cards. calculate the probulatiy that the card will be​

Answer 1

Answer:

Answer -

1) To find probability of a king of red colour in a deck of card - P(kr)

P(kr) = (Number of Kings of red colour) / Total Number of cards

P(kr) = 2 / 52

P(kr) = 0.0384 ...... (1)

2) To find probability of a face card - P(f)

P(f) = Number of face cards in a deck / Total Number of card

∵ Total number of face cards = 4 kings +

4 queens + 4 Jacks = 12

∴ P(f) = 12 / 52

P(f) = 0.2307 ....... (2)

3) To find probability of a red face card P(fr)

P(fr) = Number of Red face cards in a deck / Total Number of card

∵ Total number of Red face cards = 2 kings + 2 queens + 2 Jacks = 6

∴ P(fr) = 6 / 52

P(fr) = 0.1154 ....... (3)

4) To find the probability of the jack of hearts P(Jh)

As there is only one jack of hearts in the deck

P(Jh) = 1 / 52

P(Jh) = 0.0192 ...... (4)

5) To find probability of a spade card P(s)

P(s) = Number of Red face cards in a deck / Total Number of card

∵ Total number of Spade cards = 13

∴ P(s) = 13 / 52 = 1/4

P(s) = 0.25 ....... (5)

6) To find probability of a Queen of Diamonds = P(Qd)

P(Qd) = Number of Queens of Diamonds in a deck / Total Number of cards

∵ There is only one queen of diamonds in the deck,

∴ P(Qd) = 1 / 52

P(f) = 0.0192 ....... (6)
