Four cars-A, B, C, and D- are in a drag race. A, B, C have the same probability of winning and each is three times as likely to win as D. Find each car's probability of winning.

\n" ); document.write( "----
\n" ); document.write( "Probability D wins :: x
\n" ); document.write( "Probability A wins :: 3x
\n" ); document.write( "B wins................3x
\n" ); document.write( "C wins................3x
\n" ); document.write( "------------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "Sum of probabilities = 1
\n" ); document.write( "x + 3x + 3x + 3x = 1
\n" ); document.write( "10x = 1
\n" ); document.write( "x = 1/10 (prob D wins)
\n" ); document.write( "3x = 3/10 (prob each of A, B, C wins)
