Answer 1

7 blue, 5 yellow, 8 red, 4 green, 6 purple marbles.
So what is 7+5+8+4+6?

Answer 2

30

Answer 3

good so the total number of marbles is 30. We have 5 yellow marbles so we do 30-5= 25
because there are 5 yellow marbles.
25/30 is the probability of selecting a marble that isn't yellow
simplified is 5/6
