Answer:
0.2 = 20%
Step-by-step explanation:
The possibilities that give us a sum of 6 or less are:
(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)
(Total of 15 possibilities)
The possibilities that have a sum of 4 are:
(1,3), (2,2), (3,1)
(Total of 3 possibilities)
So, the probability that the sum will be 4, given that the sum is less than or equal to 6 is:
P = 3/15 = 0.2 = 20%
