is not a circle?
c. If we choose one figure at random, what is the probability that the figure is red, given that the figure we chose is a
triangle?
d. If we choose one figure at random, what is the probability that the figure is a triangle, given that the figure we
chose is red? (Note: This is a different question than the previous one!)
