in each bag, there are 13 green, 19 blue, and 10 yellow blocks. in a game, a student reaches their hand into a bag and chooses a block at random. what is the probability of choosing a green block?

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.
