Harvey has a fair eight-sided cube that has a different number from 1 to 8 on each side.  If he rolls this die twice, what is the probability that the second number rolled is greater than or equal to the first number?  Express your answer as a fraction.  SHOW OR EXPLAIN how you got your answer.


Answer to week 8:
