Suppose you roll a six-sided die two times hoping to get two numbers whose sum is less than 4. What is the sample space? How many favorable outcomes are there?
How many ways can you make a sum with two integers 1..6 that is less than 4? 1+1 = 2 1+2 = 3 Those are the only two combinations, right? How many different ways can you do that by rolling a 6-sided die? Hint: the order matters...
It may help to make a little table showing all of the possible outcomes: First Second Favorable 1 1 yes 1 2 yes 1 3 no 1 4 no 1 5 no 1 6 no 2 1 yes 2 2 no etc. Disregard earlier hint, I was thinking of something else...
