Question

Two dice are rolled. Find the probability that the sum of the numbers on the two dice is 4.


21/65

1/6

1/12

5/36

Answer 1

1/12

there are 6 faces of dice :1,2,3,4,5,6
total no. of faces(N)= 6
to make four it should= (1+2) (2+2) (3+1)
total no of dice(n) = 2
formula=
$N^{n}$
probability= 3/36
=1/12
