A jar contains 3 red balls and 2 green balls. You draw one ball at random. Determine the probability of selecting
a. red b. green c. blue d. red or green
p.s: the reason I am asking this questions is because we never learned about it in class and I don't know how to do it; so if you don't mind, if you could just do the first one and explain how you got it, perhaps give me a formula I should be able to do the rest on my own. I didn't post this on this site to be told that I'm stupid for needing help, and I don't appreciate that.
