Transcript text: If two fair dice, one red and one white, are rolled, in how many ways can the result be obtained?
The sum of the two dice is less than 5 .
A. 4 ways
B. 10 ways
C. 6 ways
D. 5 ways
Solution
Solution Steps
Step 1: Identify Possible Outcomes
When two dice are rolled, each die has 6 faces, resulting in a total of \(6 \times 6 = 36\) possible outcomes. We need to find the number of outcomes where the sum of the two dice is less than 5.
Step 2: List Combinations for Each Sum
We consider the possible sums less than 5: 2, 3, and 4.
Sum = 2: The only combination is (1, 1).
Sum = 3: The combinations are (1, 2) and (2, 1).
Sum = 4: The combinations are (1, 3), (2, 2), and (3, 1).
Step 3: Count the Combinations
Count the number of combinations for each sum:
Sum of 2: 1 way
Sum of 3: 2 ways
Sum of 4: 3 ways
Adding these, the total number of ways is \(1 + 2 + 3 = 6\).
