Molly is rolling a number cube with faces numbered 1 to 6 repeatedly. When she receives a 1, she will stop rolling the cube. What is the probability that Molly will roll the die less than 3 times before stopping?
Choose the correct choice.
A) 11/180 B) 125/216 C) 25/216 D) 11/216 E) 27/128
The probability that Molly will roll the die less than 4 times before stopping is the sum of the following:   The probability that Molly will roll the die once: P=1/6 (she gets 1 on the first roll);   The probability that Molly will roll the die twice: P=5/6*1/6 (not 1, 1);   P = 1/6 + 5/6*1/6 = 11/216.   Answer: 11/216.
