    Suppose that over the next several years, there will be 100 cardiac incidents at Silver's. Without a defibrillator, 30 victims will die before paramedics arrive. With a defibrillator, there is an 80% probability of saving a victim who would die without it. However, there is a 3% probability that improper use of the defibrillator will kill a victim who would have otherwise lived. Find the expected number of lives saved by the defibrillator.

    Hint: Use reasoning, not algebraic formula.
    Expected # of lives saved = Expected # still alive due to defibrillator (a medical devise) - Expected # who died due to improper use.
