Ok so assuming the board only has 4 spaces to land on (A,B,C,D) all we need to do is weight the probability,
1/4 x 1/4 x 1/4 x 1/4 x 1/4 = 1/1024
To solve I put the number of favorable outcomes over the number of total outcomes, in this case we had 1 favorable outcome each time and a constant of 4 possible outcomes.
