document.write( "The expected value, or mean, of a binomial distribution, is calculated by multiplying \r\n" );
document.write( "the number of trials (n) by the probability of successes (p), or n x p. \r\n" );
document.write( "\r\n" );
document.write( "For example, the expected value of the number of heads in 100 trials of head and tales is 50, or (100 * 0.5).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In your case, the mean value for the binomial experiment is  45*0.25 = 11.25.    ANSWER\r\n" );
