Molly is rolling a number cube with faces numbered 1 to 6 repeatedly. When she receives a 2, she will stop rolling the cube. What is the probability that Molly will roll the die less than 3 times before stopping?
Choose one:
A) 11/180  B) 11/36  C) 25/216  D) 91/216  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 2 on the first roll);   The probability that Molly will roll the die twice: P=5/6*1/6 (not 2, 2);   P = 1/6 + 5/6*1/6 = 11/36   Answer: 11/36
