A man starts at the point O on the map below. He chooses a path at random and follows it to point B1, B2, or B3. From that point

, he chooses a new path at random and follows it to one of the points A1 – A7. Suppose the man arrives at point A4, but it is not known which route he took, what is the probability that he passed through each of the three points: B1, B2, B3? Calculate each one.

Answer: 1 / 27

Detailed breakdown: p (B1) = 1 / 3

p (B2) = 1 / 3

p (B3) = 1 / 3

Probability of (B1 and B2 and B3) = 1 / 3 multiplied by 1 / 3 multiplied by 1 / 3 = 1 / 27
