Draw a tree diagram to support the area model. draw a maze that fits her plan. find p(y). explain your reasoning. find p(n). explain your reasoning. ms. sweet predicts 50 people will enter the maze next year. based on your findings, give ms. sweets a recommendation for the number of pumpkins to place in the maze.

As a tree diagram, I'd draw this with 2 branching levels. You obviously have a starting point, which branches into 3 levels for each row of the plan.

Then a second branch level off each of those 3 for the possible outcomes by the columns in that row. So the branch for the top row would have 4 further branches, the second row splits into 2 branches etc.

I'm assuming the probability is based off the area of each box, and that the splits are done equally each time.

As for drawing a maze, it's the same as the tree, just in a bit of a maze sort of shape (corners etc).

P(Y), P(N) and the number of pumpkins should come easily from the tree diagram.
