16 balls are numbered 1 to 16. A ball is drawn and then another ball is drawn without replacement. What is the probability that both balls have even numbers?
Choose the correct option:
A) 4/11
B) 5/17
C) 6/25
D) 7/30
E) 8/37
P(1st ball is even) = 8/16   P(2nd ball is also even) = 7/15   P(both balls are even) = 8/16 * 7/15 = 7/30   The answer is 7/30.
