Question

If two dice are rolled together, what is the probability that the sum of the dice is less than 7?
A.1/2
B.5/12
C.7/12
D.13/36

Answer 1

D) 13/36

Because the possible outcomes are (1,1 )(1,2)( 1,3 )(1,4)( 1,5 )(1,6)( 2,1 )(2,2 )(2,3 )(2,4 )(2,5) (2,6 )(3,1)( 3,2)( 3,3)( 3,4)( 3,5 )(3,6 )(4,1 )(4,2)( 4,3 )(4,4 )(4,5 )(4,6 )(5,1 )(5,2)( 5,3 )(5,4 )(5,5) (5,6)( 6,1 )(6,2 )(6,3)( 6,4)( 6,5 )(6,6)

Now the favorable outcomes

(1,1) (1,2)( 1,3 )(1,4 )(1,5)( 2,1)( 2,2 )(2,3 )(2,4)( 3,1)( 3,2)( 3,3)( 4,1 )(4,2)( 5,1 )

I am getting it as 15 ...can u spot if there r any errors
