Please help! The probability is 1 in 4,000,000 that a single auto trip in the US will result in a fatality. Over a lifetime, an average US driver takes 50,000 trips.

\n" ); document.write( " This is what was figured out:
\n" ); document.write( "1death/4,000,000 trips = x deaths /50,000
\n" ); document.write( "4,000,000x = 50,000
\n" ); document.write( "x=50,000/4,000,000
\n" ); document.write( "x=.0125 or 1.25%\r
\n" ); document.write( "\n" ); document.write( "------------------
\n" ); document.write( "Comment: Keep in mind that x is a probability, not a count.
\n" ); document.write( "x = (5000)*1/400,000 = 0.0125
