8. On January 30, 1835, Richard Lawrence entered the Capitol Building and aimed two pistols at President Andrew Jackson in an attempt to assassinate him.  However, both pistols misfired and Jackson beat Lawrence with his cane before the man was arrested.  Assume that in 1835 there was a 1% chance of a pistol misfiring and that we can treat each misfire as an independent event.  What is the probability that a would-be assassin in 1835 with two pistols would fail to assassinate his target because both guns misfired?
