Anonymous users2024-01-23There are two floors of A and B, and there are 8 situations in total
A, A, B, A, B, A, B
C A B A B A B A B A B
There are 2 situations on the first floor, and the probability = the ratio of the number of situations sought to the total number of situations, so the probability of A, B and C eating on the same floor is 2 8 1 4.

(1) A chooses any restaurant, the probability is 1, B must be the same as A, the probability is 1 2, C is also the same as A, the probability is 1 2 >>>More
