You have a four-card deck containing an ace, a two, a three, and a four. You draw a random card, then put it back and draw a second random card. Use a tree diagram to calculate the probability that you draw one ace and one card that is not an ace.

Question

anonymous · Answer

tree diagram will be just the graphical part ot the following calculation
prob of ace drawing =1/4
prob of other card drawing =3/4
1/4 * 3/4  +  3/4 * 1/4 = 6/16= 3/8
