1.Mr. A has a career batting average of .325. What was the probability that would get at least one hit in five official times at bat?
\n" ); document.write( "-----
\n" ); document.write( "P(x>=1) = 1 - P(x=0) = 1 - (0.675)^5 = 1-0.1401 = 0.8599
\n" ); document.write( "==================================================================
\n" ); document.write( "2.A factory finds that on the average 20% of the bolts produced by a given machine will be defective for certain specified requirements. If 10 bolts are selected at random from the days production of this machine, find the probability that 2 or more will be defective.
\n" ); document.write( "P(2<-x<=10) = 1 - P(0<= x <=1) = binomcdf(10,0.2,1) = 0.6242
