A printing company's bookbinding machine has a probability of 0.75 for producing a perfect book. This machine used to bind three books together.
\n" ); document.write( "1) Find the probability that all three books are perfect books?
\n" ); document.write( "----
\n" ); document.write( "Binomial Prob. with n = 3 and P(perfect( = 0.75
\n" ); document.write( "P(x = 3) = 0.75^3 = 0.4219
\n" ); document.write( "-------------------------------- \r
\n" ); document.write( "\n" ); document.write( "2) Find the probability that at least one of the books are perfect?
\n" ); document.write( "P(at least one perfect) = 1 - P(all are defective)
\n" ); document.write( "----
\n" ); document.write( "= 1 - 0.25^3
\n" ); document.write( "----
\n" ); document.write( "= 0.9844
