a sales promoter offers a special price for a scanner with a printer. The probabilities that each functions satisfactorily over three years are 0.68 and 0.72 respectively.What is the probability that at the end of the three years:
\n" ); document.write( "1)both scanner and printer will function satisfactorily?
\n" ); document.write( "The events are independent so P(both) = 0.68*0.72
\n" ); document.write( "----------------------------------------------------------
\n" ); document.write( "2)only the printer will be functioning?
\n" ); document.write( "P(print only) = 0.68(1-0.72)
\n" ); document.write( "-------------------------------------
\n" ); document.write( "3) At least one of two machines will be functioning?
\n" ); document.write( "Since p(none is operating) = 0.32*0.28,
\n" ); document.write( "P(at least one) = 1- P(none) = 1 - 0.32*0.28
\n" ); document.write( "please state any assumptions made.
\n" ); document.write( "=======================
