Understanding the Problem
When two dice are thrown, one with standard faces (1 to 6) and the other with faces numbered 1, 2, 2, 3, 3, 4, we need to find the probability that their sums yield a perfect square.
Identifying Perfect Squares
The perfect squares less than or equal to the maximum sum (6 + 4 = 10) are:
- 1
- 4
- 9
Therefore, the possible perfect square sums are 1, 4, and 9.
Calculating Possible Outcomes
The total outcomes when throwing both dice are:
- Standard die: 6 outcomes
- Unique die: 6 outcomes
Total outcomes = 6 * 6 = 36.
Finding Favorable Outcomes
Now, let’s find outcomes that yield perfect square sums:
- Sum = 4:
- (1, 3), (2, 2), (3, 1) → 3 outcomes
- Sum = 9:
- (5, 4), (6, 3) → 2 outcomes
Summing these outcomes gives us 5 favorable outcomes.
Calculating Probability
The probability of rolling a perfect square sum is calculated as:
- Probability = (Number of Favorable Outcomes) / (Total Outcomes)
- Probability = 5 / 36
Final Answer
The probability of getting a sum that is a perfect square when throwing both dice is 5/36.
