Question

reviewing computing probability
if two fair dice are rolled, there are two different ways to roll a sum of 3:

die 1	die 2
2	1

how many different ways are there to roll a... (options: 2, 3, 4, 5)

Explanation:

Step1: Analyze the problem (assuming the sum is 4, as the question seems cut off but following the pattern)

To find the number of ways to roll a sum of 4 with two dice, we list the pairs \((Die1, Die2)\) where \(Die1 + Die2=4\). The possible pairs are \((1, 3)\), \((2, 2)\), \((3, 1)\).

Step2: Count the pairs

We have 3 pairs: \((1, 3)\), \((2, 2)\), \((3, 1)\). So there are 3 ways.

Answer:

3 (Assuming the question is about rolling a sum of 4, as the original question was cut off but following the pattern of the example with sum 3. If the actual sum is different, the approach would be similar: list all pairs of die faces that add to the target sum and count them.)
