i just guessed sorry
Your answer is in the attachment!!
Are the following:
AXB are all the possible pairs (a,b) where a is in A and b is in B. Then
AXB = {(x,1), (x,2), (x,3), (y,1), (y,2), (y,3)}.
Now, BXB are all the possible pairs (a,b) where a and b are in B. Then
BXB = {(1,1) (1,2), (1,3), (2,2), (2,1), (2,3), (3,1), (3,2), (3,3)}.
25/19
100/76 we can divide both the numerator and denominator by 4 to get 25/19. The decimal answer would be around 1.32.
