Hey testtrail429.

Hint: Thjnk about whether each layer probability is independent of the result at the layer before (In independent situations P(A and B) = P(A)P(B)).

In addition to chiro's comment, think about how many ways you can get to the middle slot, how many ways can you get to the others? Having calculated this, how could this help you think about the probabilities of each one?
