Answer:
0.2 = 20%
Step-by-step explanation:
The combinations that yield a total of 6 or lower include:
(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)
(15 combinations in total)
The combinations resulting in a total of 4 are:
(1,3), (2,2), (3,1)
(3 combinations in total)
Thus, the probability of obtaining a sum of 4, given that the total is 6 or less is:
P = 3/15 = 0.2 = 20%
