­                   Event A               X Event A          Subtotal

Event B           1/5                        3/5                4/5                                            

X Event B        1/5                         0                  1/5

Subtotal          2/5                         3/5                 1



4 desirable outcomes for the intersection of event A & B
=>\( 4 = \frac{1}{5}\) * total slots
=> total slots = 20

Desirable outcomes for B: \(\frac{4}{5} * 20 = 16\)­
