Problema Solution
The probability that the correct path out of a maze is straight ahead is 0.1. The probability that the correct path is left, right, or back is equally likely.
What is the probability that the correct path out of the maze is left
Answer provided by our tutors
P(straight ahead) = 0.1
P(left) = P(right) = P(back) = p
Since the events are independent we can write:
P(straight ahead) + P(left) + P(right) + P(back) = 1
0.1 + p + p + p = 1
3p = 1 - 0.1
3p = 0.9
p = 0.9/3
p = 0.3
The probability that the correct path out of the maze is left is 0.3.
