Question

Glass jar contains 6 red, 4 green, 3 blue, and 5 yellow marbles. if a single marble is chosen at random from the jar, what is the probability that it is blue or green?

Answer 1

So the total number of marbles is 18(6+4+3+5) right?
So we have 4 green and 3 blue marbles.
So together we have 7 marbles that we want to get right?
Now 7/18 is the chance that this will happen.
So ans:7/18
