P(6 or greater than 5)? 

The only way to roll a number greater than 5 is to roll a 6.

So that asks P(6 or 6) which is the same as P(6) = "1 way out of 6" = 1%2F6

Answer: 1%2F6

---------------------------------------

You can use the formula, but why bother?  I'll do it anyway:

P(A or B) = P(A) + P(B) - P(A and B)

P(6 or 6) = P(6) + P(6) - P(6 and 6)

P(6 or 6) = 1%2F6 + 1%2F6 - 1%2F6 = 1%2F6
