The score 4 can occur in four differenet ways: first dice 5 second dice
1,
first dice 1, second dice 5, first dice 6 second dice 2, first dice 2
second
dice 6.  Each of the four combinations can occur at probability
(1/6)(1/6)
= 1/36.  Thus, the probability of getting 4 is 4/36 = 1/9.

Dan, 

It seems to me that the reason you may have "forgot" everything
you learned in Algebra II may have to do with your method of completing
homework assignments, i.e. getting others to do your work for you.  Try
to do your own work, think about the problem.  This is not a hard problem
at all.  Personally I would be a bit embarrassed to ask such a lame
question in a public forum.  Do your own work and _learn_ from your
mistakes.  


-right
marty

in fact it's a simple and straight question

there is only 36 combinations if u throw two dice.

the answer is  (no of combination that the difference is 4) / 36
