Algebra.Com's Answer #52822 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! When a pair of dice is rolled, the total will range from 2 (1,1) to 12 (6,6). It is a fact that some numbers will occur more frequently than others as the dice are rolled over and over. \n" ); document.write( "Why will some numbers come up more frequently than others? \n" ); document.write( "Because combinations of two die sometimes give few occurrences of some numbers \n" ); document.write( "and more frequest occurrence of others. \n" ); document.write( "---------------- \n" ); document.write( "Each die has six sides numbered from 1 to 6.
