P(Both got C's) = P(One student got a C)*P(Another student got a C)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "P(Both got C's) = 0.6 * 0.6 .... Note: 0.6 is the decimal equivalent of 60%\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "P(Both got C's) = 0.36\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the probability that both got C's or better is 36% \n" ); document.write( " |
