Algebra.Com's Answer #167019 by stanbon(75887) ![]() You can put this solution on YOUR website! Blood type AB is found in only 3% of the population. If 225 people are chosen at random, what is the probability that \n" ); document.write( "--- \n" ); document.write( "It's a binomial problem with n = 225 and p = 0.03 \n" ); document.write( "------------------ \n" ); document.write( "a) 5 or more will have this blood type? \n" ); document.write( "Solve P(5 <= x <= 225) = 1 - binomcdf(225,0.03,4) = 0.8072 \n" ); document.write( "------------------------ \n" ); document.write( "b) Between 5 and 10 will have this blood type? \n" ); document.write( "Solve P(5 <= x <= 10) = binomcdf(225,0.03,10) - binomcdf(225,0.03,4) \n" ); document.write( "= 0.7286 \n" ); document.write( "==================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
