\n" ); document.write( "This is a straightforward application of binomial probability. The probability that a particular camera is faulty is 0.075, so the probability that it is not defective is 0.925.

\n" ); document.write( "You won't learn anything by having us do the calculations for you, so I leave that to you. Here is what you need

\n" ); document.write( "\"P%28x=0%29+=+%284C0%29%2A%280.075%29%5E0%2A%280.925%29%5E4\"

\n" ); document.write( "\"P%28x=1%29+=+%284C1%29%2A%280.075%29%5E1%2A%280.925%29%5E3\"

\n" ); document.write( "\"P%28x=2%29+=+%284C2%29%2A%280.075%29%5E2%2A%280.925%29%5E2\"

\n" ); document.write( "\"P%28x=3%29+=+%284C3%29%2A%280.075%29%5E3%2A%280.925%29%5E1\"

\n" ); document.write( "\"P%28x=4%29+=+%284C4%29%2A%280.075%29%5E4%2A%280.925%29%5E0\"

\n" ); document.write( "To check your calculations you can verify that the sum of those probabilities is equal to 1.
