Algebra.Com's Answer #373593 by stanbon(75887) ![]() You can put this solution on YOUR website! 1. It is asserted that 65 percent of the cars approaching an individual toll both in New Jersey are equipped with an E-ZPass transponder. \n" ); document.write( "Binomial Problem with n = 7; p(have) = 0.65 ; p(not have) = 0.35 \n" ); document.write( "------------------------------\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Find the probability that in a sample of seven cars: \n" ); document.write( "(a) All seven will have the transponder.
