Question 388907
The answer depends on whether you are selecting with replacement of the selected numbers or without replacement of the selected numbers.
===
In order for the two numbers to sum to 3, the numbers selected must be 1 and 2.
--
Without replacement:
Probability of selecting 1 and 2=P(1,2)+P(2,1)=1/8*(1/7)+1/8*(1/7)=2/56=1/28
--
with replacement:
P(1,2)+P(2,1)=1/8*(1/8)+1/8*(1/8)=2/64=1/32
