Algebra.Com's Answer #74625 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! If three coins are tossed what is the probability of tossing two heads and one tail? \n" ); document.write( "---------- \n" ); document.write( "There are three ways to place the tail so those three are mutually \n" ); document.write( "exclusive events. The probability of each event is (1/2)^2*(1/2) \n" ); document.write( "because each coin is independent = 1/8 \n" ); document.write( "So the answer is 1/8 + 1/8 + 1/8 = 3/8 \n" ); document.write( "------------ \n" ); document.write( "Using the binomial formula you would get 3C2(1/2)^2(1/2) = 3(1/8) = 3/8\r \n" ); document.write( "\n" ); document.write( "==================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
