Bunuel, shouldn't the answer be 3/10, since I can pick a card from bowl X first or from bowl Y first, as the sequence is not specified. Thanks in advance for your responce.

Bowl X has 4 cards in it, numbered 1 - 4. Bowl Y has 5 cards in it, numbered 5 - 9. What is the probability that the sum of a card pulled randomly from Bowl X and a card pulled randomly from Bowl Y will equal 8?

A. 1/20
B. 1/10
C. 3/20
D. 2/16
E. 3/16

The total number of combinations (of a card drawn from Bowl X and another from Bowl Y) is 4 x 5 = 20. Of these 20 combinations, the ones that yield a sum of 8 are: 1 and 7, 2 and 6, and 3 and 5.

Therefore, the probability of getting a sum of 8 is 3/20.

Answer: C
