Question:

A monkey is given 12 blocks: 3 shaped like squares, 3 like rectangles, 3 like triangles, and 3 like circles. If it draws three of each kind in order-say, 3 triangles, then 3 squares, and so on-would you suspect that the monkey associates identically shaped figures? Calculate the probability of this event.
