If 10% of the rivets produced by a machine are defective, find the probability that out of 5 randomly chosen rivets:
\n" ); document.write( "The problem is \"binomial\" because the rivets are defective or not defective.
\n" ); document.write( "P(defective)=0.10; P(not defective)=0.90
\n" ); document.write( "(i) P(one or more will be defective) = 1 - P(none are defective)
\n" ); document.write( "1-(0.90)^5
\n" ); document.write( "= 0.40951
\n" ); document.write( "-----------
\n" ); document.write( "If you use a TI calculator it is \"1 - binompdf(5,0.1,0)\"
\n" ); document.write( "========================\r
\n" ); document.write( "\n" ); document.write( "(ii)P(at most two will be defective)
\n" ); document.write( "=P(x=0)+P(x=1)+P(x=2)
\n" ); document.write( "=binomcdf(5,0.1,2)=0.99144
\n" ); document.write( "==========
