Answer 1

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:

$6*6 =36$

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

$A = \{(1,6), (2,5), (3,4) , (4,3) , (5,2), (6,1)\}$

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:

$P(A) = \frac{n(A)}{n(S)}\\\\=\frac{6}{36}\\\\=\frac{1}{6}$

Hence,

The probability for rolling a sum of 7 is: 1/6
