A computer shop builds PC'S from shipments of parts it receives from various suppliers. The number of defective hard drives per shipment is to be modeled as a random variable X. The random variable is assumed to have the following distribution:
\n" ); document.write( "X _________ P(x)
\n" ); document.write( "0 _________ 0.55
\n" ); document.write( "1 _________ 0.15
\n" ); document.write( "2 _________ 0.10
\n" ); document.write( "3 _________ 0.10
\n" ); document.write( "4 _________ 0.05
\n" ); document.write( "5 _________ 0.05
\n" ); document.write( "=========================
\n" ); document.write( "What is the probability that a shipment will have
\n" ); document.write( "more than two defective hard drives?\r
\n" ); document.write( "\n" ); document.write( "P(more than 2) = P(x=3)+P(x=4)+P(x=5) = 0.10+0.05+0.05 = 0.20
