A standard deck of playing cards contains 52 cards in four suits of 13 cards each. Two suits are red and two suits are black. Find each probability.Assume the first card is replaced before the second card is drawn.

1.P(black,queen)
2.P(jack,queen)
How would I solve these type of problems?

  • Math -

    If you replace the first card and shuffle before drawing the second the two drawings are independent and the chance of black, queen is the product of the queen probability and the black probability.
    (4/52)(1/2) which is 2/52
    which you could have said immediately because there are 2 black queens in a deck of 52 cards.

  • Math -

    May I ask where did you get 4/52 and 1/2?

  • Math -

    Four out of 52 cards are queens.
    1/2 of all the cards are black.
