Algebra.Com's Answer #297650 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! a recent report stated that 4% of adults cut their sandwhich in half before eating it. \n" ); document.write( "if 10 u.s. adults are selected randomly, \n" ); document.write( "--- \n" ); document.write( "Binomial Problem with n= 10 and p = 0.04 \n" ); document.write( "-------\r \n" ); document.write( "\n" ); document.write( "what is the probability that \n" ); document.write( "a) at least 6 people cut their sandwhich in half before eating \n" ); document.write( "Ans: P(6<= x <=10) = 1-binomcdf(10,0.04,5) = 0.00000074824 \n" ); document.write( "-------- \n" ); document.write( "b) at most 3 people cut their sandwhich in half before eating it \n" ); document.write( "Ans: binomcdf(10,0.04,3) = 0.9996 \n" ); document.write( "========= \n" ); document.write( "c) (use binomial formula) exactly 4 people cut their sandwhich in half before eating it \n" ); document.write( "P(x= 4) = 10C4*(0.04)^4*(0.96)^6 = binompdf(10,0.04,4) =0.0004208 \n" ); document.write( "============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "================ \n" ); document.write( " \n" ); document.write( " |
