James lives in san francisco and works in mountain view. in the morning, he has 3 transportation options (bus, cab, or train) to work, and in the evening he has the same 3 choices for his trip home. if james randomly chooses his ride in the morning and in the evening, what is the probability that he'll take the same mode of transportation twice?

Hey,to find the probability that james will take the same mode of transportation in the morning and in the evening would be 1/9. since each mode of transportation appears once, and only one, we can pick anyone as an example and find the probability. that probability will apply in all cases. let's use the cab as an example. to find the probability multiply the probability of getting the cab in the morning to getting the cab in the evening.morning:   evening:   final answer:   cheers,izzy
