An urn contains 4 balls: 1 white, 1 green, and 2 red. we draw 3 balls with replacement. find the probability that we do not see all three colors. hint: one way to do this is to define event w = {white ball did not appear}. similarly define events r and g for red and green balls. now use inclusion-exclusion. there are other ways.

I’m pretty sure the slope would be 1 since the x and y values increase by 1

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
