Look at all of totality of outcomes.
\n" ); document.write( "There are \"2%5E3\" or \"8\" of them.
\n" ); document.write( "1.H H H
\n" ); document.write( "2.H H T
\n" ); document.write( "3.H T H
\n" ); document.write( "4.H T T
\n" ); document.write( "5.T H H
\n" ); document.write( "6.T H T
\n" ); document.write( "7.T T H
\n" ); document.write( "8.T T T
\n" ); document.write( "Now that you have all of the outcomes, you can answer all of your questions.\r
\n" ); document.write( "\n" ); document.write( "1. \"at most two heads\"-Means 2 H or less.
\n" ); document.write( "Count the number of outcomes that have 2 H or less.
\n" ); document.write( "There are 7 possible outcomes(2,3,4,5,6,7,8).
\n" ); document.write( "The probability is possible outcomes divided by total outcomes.
\n" ); document.write( "\"P=7%2F8\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "2. At least 1 H- Again there are 7 of them (1,2,3,4,5,6,7)
\n" ); document.write( "\"P=7%2F8\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Now complete the remaining questions in a similar way.\r
\n" ); document.write( "\n" ); document.write( "
