You first add up how many erasers there are in the bag so there are 20 and then you check how many purple erasers there are and so there are 5 and so the answer is 5/20 or 1/4 which is 0.25 as a decimal and if you do probability the answer has to be in between o and 1 and so 0.25 is in between 0 and 1 so it should be correct
