Algebra.Com's Answer #460107 by stanbon(75887) ![]() You can put this solution on YOUR website! In a small town, 60% of the households have dogs. If 5 households are randomly selected, what is the probability that at least 4 of them have dogs? \n" ); document.write( "----- \n" ); document.write( "Binomial Problem with n = 5 and p(have dog) = 0.6 \n" ); document.write( "----- \n" ); document.write( "P(4<= x <=6) = 1 - P(0<= x <=3) = 1 - binomcdf(5,0.6,3) = 0.3370 \n" ); document.write( "============ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "=============== \n" ); document.write( "A. 0.8 \n" ); document.write( "B. 3 \n" ); document.write( "C. 0.337 \n" ); document.write( "D. 0.259 \n" ); document.write( " \n" ); document.write( " |
