Question 1201433
<br>
One basic method for computing probabilities like this is to find the probability that you can still get the desired outcome when the first person chooses a restaurant, then find the probability that you can still get the desired outcome when the second person chooses a restaurant, then multiply the two probabilities.<br>
The first person can choose any of the 3 restaurants; the probability that we can still get the desired outcome after the first person chooses a restaurant is 3/3 = 1.<br>
Then to get the desired outcome, the second person has to choose the same restaurant as the first person; there are 3 restaurants to choose from, and only 1 will give the desired outcome.  So the probability that the second person makes a choice that will result in the desired outcome is 1/3.<br>
And the probability of obtaining the desired outcome is then the product of the two probabilities: (1)*(1/3) = 1/3.<br>
ANSWER: 1/3<br>
