Question

a psychologist has constructed the following maze for use in an experiment. the maze is constructed so that a rat must pass through a series of one - way doors. how many different paths are there from start to finish? 10 × different paths start finish maze resources (book)

Explanation:

Step1: Count first segment paths

From start, there are 3 possible paths to the next section.

Step2: Count second segment paths

Each of those paths connects to 3 paths in the middle section.

Step3: Count third segment paths

Each middle path connects to 2 paths to the finish.

Step4: Calculate total paths

Multiply the number of paths in each segment: $3 \times 3 \times 2$

Answer:

18 different paths
