If 3 dice are rolled at the same time, what is the probability of all 3 dice showing even face \n" ); document.write( "values? (i.e. all 3 dice showing 2, 4, or 6) \n" ); document.write( " \r\n" ); document.write( "\r\n" ); document.write( "We calculate the numerator of the desired probability:\r\n" ); document.write( "\r\n" ); document.write( "There are 3 ways an even number can show up on the first die\r\n" ); document.write( "AND\r\n" ); document.write( "There are 3 ways an even number can show up on the second die\r\n" ); document.write( "AND\r\n" ); document.write( "There are 3 ways an even number can show up on the third die\r\n" ); document.write( "\r\n" ); document.write( "So since \"AND\" means \"MULTIPLY\", there are 3x3x3 or 27 ways\r\n" ); document.write( "the three dice can all come up even.
