In testing a new drug, researchers found that 1% of all patients using it will have a mild side effect. A random sample of 12 patients using the drug is selected . Find the probability that:
\n" ); document.write( "Binomial problems with n = 12 and p(side effect) = 0.01
\n" ); document.write( "---------------------------------
\n" ); document.write( "A. Exactly one will have this mild side effect
\n" ); document.write( "P(x = 1) 12C1*0.01^1*0.99^11 = binompdf(12,0.01,1) = 0.1074
\n" ); document.write( "--------------------------------------------------------------
\n" ); document.write( "B. at least one will have this mild effect.
\n" ); document.write( "P(x >= 1) = 1 - P(x = 0) = 1 - 0.99^12 = 0.1136
\n" ); document.write( "===================================================
