Answer
60 outcomes
Work Step by Step
A sum of 8 can be obtained by: (1,7) or (2,6) or (3,5) or (4,4),
sum of (1,7) can be obtained $4\times4=16$ times,
sum of (2,6) can be obtained $4\times4=16$ times,
sum of (3,5) can be obtained $4\times4=16$ times,
sum of (4,4) can be obtained $4\times3=12$ times,
so the outcomes in A are 16+16+16+12=60
