The probability for rolling a sum of 7 is: 1/6
Step-by-step explanation:
Given that two six-sided dies are rolled the total outcomes will be:
n(S) = 36
Out of total outcomes we have to count the outcomes that sum up to 7
Let A be the event that the sum of outcomes is 7
Here the first number is the result of first die and second number is the result of 2nd die.
n(A) = 6
So the probability of A will be:
Hence,
The probability for rolling a sum of 7 is: 1/6
