Mark the correct alternative in each of the following: A box contains 3 orange balls, 3 green balls and 2 blue balls. Three balls are drawn at random from the box without replacement. The probability of drawing 2 green balls and one blue balls is

Question

Philoid · Accepted 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 2^nd 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)
