select the correct answer. two 6 - sided dice are rolled at the same time. how many outcomes correspond to the event that the sum of the numbers is 5?
Answer
Explanation:
Step1: List all possible pairs
Let the outcomes of the first die be (x) and the second die be (y), where (1\leq x\leq6) and (1\leq y\leq6). We want (x + y=5).
Step2: Find valid pairs
When (x = 1,y = 4); (x = 2,y = 3); (x = 3,y = 2); (x = 4,y = 1).
Answer:
4
