probably wrong but...

if you treat each pull of the trigger as an independent event then the probability of each pull is:

A: 1: 0.166666667
B: 2: 0.2
A: 3: 0.25
B: 4: 0.333333333
A: 5: 0.5
B: 6: 1

Then if you do 100 trials at each slot you get:
A: 1: 16.6666667
B: 2: 20.
A: 3: 25.
B: 4: 33.3333333
A: 5: 50.
B: 6: 100

Adding the total up yields 245 "kills"
A dies: 91.66666667 (37.4% of the time)
B dies: 153.3333333 (62.6% of the time)

It does not seem right though, I would think it would be closer to 50/50 if not exactly.
