Question

Allison is going for a walk along the streets of a city. Three times, she will decide at random whether to turn left or right. What is the probability that she will turn left, turn right, and then right again

Answer 1

Answer: The probability would be 1/8 or 0.125 or 12.5%

Step-by-step explanation: Since Allison has two choices (left or right) at each turn, there are a total of 222= 8 possible outcomes for the three turns. These outcomes can be listed as the following: LLL,LLR,LRL,LRR,RLL,RLR,RRL,RRR.

Out of these eight outcomes there is only one outcome that matches the desired sequence of turning left, then turning right, and then again, which is RRR.Therefore, the probability that Allison will turn left, turn right, and right again is 1/8 or 0.125 or 12.5%.
