At a political rally there are 20 republicians 13 democrates 6 independents. if a person is chosen at random what is the probability that the person is either a democrate or and independent?

MathMate,
"at random" means all choices have equal probability.
Sample space = 20+13+6=39
There are 13 democrates and 6 independents for a total of 19.
What is the probability?

19/39

it would be 19 over 39. Good luck~!:)
