\n" ); document.write( "Hi,
\n" ); document.write( "Note: Use of [(nCx) * p^x * q^(n-x)] below:
\n" ); document.write( "P(0 heads in 5 flips)
\n" ); document.write( "Note: The probability of x successes in n trials is:
\n" ); document.write( "\"P+=+nCx%2Ap%5Ex%2Aq%5E%28n-x%29\" where p and q are the probabilities of success and failure respectively.
\n" ); document.write( "In this case \"p%28heads%29+=+.5\" & q(tails) = 1/2 or .5
\n" ); document.write( "nCx = \"n%21%2F%28x%21%28n-x%29%21%29\" \"n+=+5\" and \"x+=+0\"
\n" ); document.write( "P = 5C0(.5)^0(.5)^5 = 1(.5)^0(.5)^5 = \"+.0313\" \n" ); document.write( "
\n" );
