A would be c(800)=600.
B would be c(200)=e.
C would be c(s)=900.
If the bird were just guessing there would be two options (right or wrong) and we would expect them to be equally likely to occur (50% chance for each). A 50% of correct, out of 12 cards gives us:
12×0.50=6
If the bird was guessing we would expect 6 correct answers. (1/2 of the total correct and 1/2 wrong.)
So the answer would be 6.
