Agroup of 10 fisherman enjoy certain types of fish, 3 of them like salmon, 5 like trout and 2 like bass. a single fisherman is chosen at random. what is the probability that the fisherman likes salmon or bass?

a. 1/10
b. 47/90
c. 3/50
d. 1/2

It is D, as 2 plus 3 is 5 which is half of 10.

This does not make sense

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
