You have a 4-card deck containing a queen, a jack, a 10, and a 9. You draw a random card, put it back, and draw a second random card. Use a tree diagram to calculate the probability that you draw exactly 1 face card (a queen or a jack).

A. 1/2.

B. 7/16.

C. 1/4.

D. 9/16.

  • Probability -

    I cannot draw a tree diagram here.

    If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

    Face card = 2/4 = 1/2

    Non-face card = 2/4 = 1/2
