Find the odds against obtaining two (2) heads in a single toss of two coins.\r
\n" ); document.write( "\n" ); document.write( "\"Odds against event A\" = [P(not A)]/[P(A)]\r
\n" ); document.write( "\n" ); document.write( "P(2 heads) = 1/4
\n" ); document.write( "P( not 2 heads) = 3/4\r
\n" ); document.write( "\n" ); document.write( "Therefore Odds against 2 heads = (3/4)/(1/4) = 3:1\r
