probability would be .03 + .05 - .03 * .05\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( ".03 is the probability that one will break down.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( ".05 is the probability that the other will break down.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( ".03 * .05 is the probability that both will break down.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the probability that exactly one will break down is the probability that one will break down or the other will break down minus the probability that both will break down.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that equals .03 + .05 - .03 * .05 = .0785\r
