7 handle fails\

4) Our old reusable shopping bag has 2 canvas handles. They are both old, though, so they have a 20% chance to break every day. If one breaks, then we can still carry the bag, but the remaining handle has to carry all the weight, so it has a 25% chance to break. What is the Probability of our shopping bag hitting the ground? [Hint: Let A = "First handle fails", B = "Second handle fails", and then we need to find P(AnB).]
