On the average, 4 out of 5 of the people who register for a fitness program work hard to achieve intended results. If 4 registered patrons were selected at random, what is the probab1ility that more than 2 will be ones who have worked hard to achieve their intended goals?
\n" ); document.write( "---
\n" ); document.write( "Binomial Problem with n = 4 and p(work hard) = 4/5 = 0.8
\n" ); document.write( "P(3<= x <=4) = 1 - P(0<= x <=2) = 1 - binomcdf(4,0.8,2) = 0.8192
\n" ); document.write( "------------------------------------------
