A single card is chosen at random from a standard 52-card deck. Find the odds against its being a
\n" ); document.write( "1.heart,
\n" ); document.write( "Prob(picking a heart)=1/4; Prob(not picking a heart)=3/4
\n" ); document.write( "Odds against its being a heart = (3/4)/(1/4)= 3 to 1
\n" ); document.write( "-------------------------------
\n" ); document.write( "2.a red queen,
\n" ); document.write( "Prob(getting red queen)=2/52; Prob(not getting red queen)=50/52
\n" ); document.write( "Odds against getting red queen = (50/52)/(2/52) = 50 to 2 or 25 to 1
\n" ); document.write( "-------------------------
\n" ); document.write( "3. a king or a black face card.
\n" ); document.write( "Prob(getting king or black face card)=[4+6-2]/52=8/52=4/26
\n" ); document.write( "Prob(not getting king or black face card)=22/26
\n" ); document.write( "Odd against getting king or black face card = 22/4= 11 to 2
\n" ); document.write( "----------
\n" ); document.write( "In general Odds against A = [P(not A)]/P(A)]
