Given :
Total counters in a bag = 20
Red counters = 3
Blue counters = 2
Yellow counters = 5
Green counters = 20 - 3 - 2 - 5
= 10
Probability = Favorable outcome/Total outcome
Green + yellow counters = 10 + 5
= 15
So, probability of getting yellow or green counter = 15/20
= 0.75
Hence, probability of getting green or yellow counters is 0.75
