Probability
posted by so confused! on .
You have a 4card 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.

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
Nonface card = 2/4 = 1/2
