I get D.

There are only 5 ways to get a sum of 8:

2 6
6 2
3 5
5 3
4 4

Two of these ways have 5's in them. So 2/5 probability.

2/5.

The sum of the numbers on the cards is 8.
(2,6)
(3,5)
(4,4)
(5,3)
(6,2)======5

One of the two cards drawn is numbered 5.
(3,5)
(5,3)======2

Hence, No. of favorable outcomes/Total Outcomes = 2/5.
