You can put this solution on YOUR website!
A DIE HAS 6 FACES.WHEN IT IS ROLLED ANY FACE CAN TURN UP.SO IN ONE THROW WE CAN GET 5 ONLY IN ONE OUT OF 6 CHANCES OR PROBABILITY OF 1/6.
\n" ); document.write( "FOR NOT GETTING A 5 ,THE PROBABILITY =5/6 ...WE SAY PROBABILITY OF SUCCESS=P=1/6
\n" ); document.write( "SINCE THAT IS WHAT WE WANT.
\n" ); document.write( "PROBABILITY OF FAILURE =Q=5/6
\n" ); document.write( "NOW WE USE BINOMIAL DISTRIBUTION THEOREM TO FIND PROBABILITY IN MANY TROWS OR 5 THROWS AS REQUIRED HERE.IT SAYS
\n" ); document.write( "PROBABILITY OF EXACTLY R SUCCESSES IN N TRIALS =(NCR)*(P^R)*(Q^(N-R))
\n" ); document.write( "WE HAVE N=5 AND R=1,P=1/6...Q=5/6
\n" ); document.write( "P(1)=5C1*((1/6)^1)*((5/6)^4)=(5*5*5*5*5)/(6*6*6*6*6)=0.4019
\n" ); document.write( "
\n" );
