Select the favorable outcomes for rolling a sum less than five
Question
Answer:
We want the sum of the two rolls to be less that five.Therefore, we will examine each given set of choices and choose the one where all the points have a sum less than 5.
First set: all the point are 5 added to another number. Therefore, the sum is definitely not less than 5. This choice is rejected.
Second set: We have two points having 6 added to a number. Therefore, this choice is also rejected.
Third set: We have the points (5,5) and (6,6) which have a sum greater than 5. Therefore, this set is also rejected.
Fourth set: We have:
(1,1) with sum = 2
(1,2) with sum = 3
(1,3) with sum = 4
(2,1) with sum = 3
(2,2) with sum = 4
(3,1) with sum = 4
Therefore, all sums are less than 5. This is the correct choice.
Based on the above, the correct option is the last one.
