Fewer than 2 is 0 or 1
\n" ); document.write( "p(0) defective is 0.97^10=0.7374
\n" ); document.write( "p(1) defective is 10*0.97^9*0.03=0.2281
\n" ); document.write( "the answer is the sum of the probabilities or 0.9655
\n" ); document.write( "-
\n" ); document.write( "more than 2 items will be defective is 1- probability p(0,1,2)
\n" ); document.write( "calculator is 1-binomcdf(10,0.03,2)=0,0028. The 1- comes from the fact that the binomial function computes from the left side, and we want the right side for the answer.
\n" ); document.write( "p(2)=45*0.97^8*0.03^2=0.0317
\n" ); document.write( "add that to the first answer to get 0.9972, probability 0,1,2 items are defective.
\n" ); document.write( "The answer is 1-0.9972 or 0.0028
\n" ); document.write( "binompdf is a good one to remember, because that will give you the specific value, since remembering the top value to use for the interval can sometimes be confusing.
\n" ); document.write( "
\n" );
