Question
What is the probability of getting a sum 9 from two throws of a dice?
Choices:
- 1/2
- 3/1
- 3/4
- 1/3
Solution
To solve this problem, we need to understand that a die has 6 faces, so when two dice are thrown, there are a total of 6*6 = 36 possible outcomes.
Next, we need to find out in how many ways we can get a sum of 9. The pairs that give a sum of 9 are: (3,6), (4,5), (5,4), (6,3). So, there are 4 favorable outcomes.
The probability of an event is given by the ratio of the number of favorable outcomes to the total number of outcomes.
So, the probability of getting a sum of 9 from two throws of a dice is 4/36 = 1/9.
None of the given choices match the correct answer.
