We can use the binomial probability formula to solve this problem since either a student voted or not voted
\n" ); document.write( ":
\n" ); document.write( "Probability(P) (k events in n trials) = nCk * p^k * (1-p)^(n-k), where nCk = n! / (k! * (n-k)!)
\n" ); document.write( ":
\n" ); document.write( "p = 0.20, k=5, n=10
\n" ); document.write( ":
\n" ); document.write( "P = 10C5 * (0.20)^5 * (1-0.20)^(10-5) = 0.0264
\n" ); document.write( ":
\n" ); document.write( " \n" ); document.write( "

\n" );
