25% of 400 is 100.

It means that there are 100 red jelly beans and 300 belly jeans of a different colour in the bag.

Your chance of picking a jelly bean out of the bag which isn't red is 300/400. 300/400 is equal to 75% therefore the chance of not selecting a red jelly bean out of the bag is 0.75.
