Question

The probability that a blue marble is drawn out of a bag is 3/5. What is the probability that a blue marble is not drawn?

Answer 1

2/5, If the 3/5 is being taken by the blue marble the other 2 marbles will be used to add up to 5. So the remaining marbles would be 2/5

Answer 2

The probability of a blue marble not to be drawn is 2/5

There are 5 marbles in the bag and 3 of them are blue. So to find out the probability of one not being drawn we would take 5/5-3/5 which is equal to 2/5.

Hope this helped! :D
