A pair of dice is rolled, one is red other is green. Find the probability that the sum is 6
5/36
1+5=6
2+4=6
3+3=6
4+2=6
5+1=6
5/36 is correct
To find the probability that the sum of the two dice is 6, we can consider all the possible outcomes and count how many of them have a sum of 6.
First, let's determine the total number of outcomes when rolling two dice. Each die has six sides, so the total number of outcomes is 6 multiplied by 6, which is 36.
Next, let's list the possible outcomes that result in a sum of 6:
- Red die: 1, Green die: 5
- Red die: 2, Green die: 4
- Red die: 3, Green die: 3
- Red die: 4, Green die: 2
- Red die: 5, Green die: 1
There are a total of 5 favorable outcomes for a sum of 6.
Now, we can calculate the probability by dividing the number of favorable outcomes by the number of total outcomes:
Probability = Number of favorable outcomes / Number of total outcomes
Probability = 5 / 36
Therefore, the probability that the sum of the two dice is 6 is 5/36 or approximately 0.139, which can also be written as a percentage of approximately 13.9%.
