Question

probability of getting the sum 4 when a pair of dice is rolled

Answer 1

HOLA sis!!
Rajdeep here.....

A pair of dice is rolled, so two dices are rolled.
In one dice, there are six surfaces.

Since two dice are rolled,
Total Possible Outcomes (TPO) = 6² = 36

Now, outcomes in which sum will be 4:
(1,3), (2,2), (3,1)

So, number of favourable outcomes (NFO) = 3 (Since there are three chances).

Now, Probability = NFO/TPO
= 3/36
= 1/12

Hence, the probability is 1/12

Thanks!!
Hope my answer is satisfactory (^_^)
