A box contains red markers, blue markers amd green markers. there are more blue makers than red the probability of randomly selecting a blue marker from the box is 1/5. that is a possible probability that a randomly selected marker from he box is red?

We are given with three markers which means the probability of finding all these three markers add up to 1. if the probability of finding a blue marker is 1/5 which is greater in number than the red marker, then the probability must be less than 1/5, i. e. 1/10.
