Answer :

P(G) = Probability of drawing a green ball =


P(B) = Probability of drawing a blue ball =


P(O) = Probability of drawing an orange ball =


Important When taking the probability of green/ball in 2nd draw, remember to reduce the total number of balls and number of green/blue ball


While finding the probability. Example – P(GGB) =


Now Probability of drawing 2 green balls and one blue ball :


P = P(GGB) + P(GBG) + P(BGG)
