A bag contains three green marbles,

Question:

A bag contains three green marbles, four blue marbles, and two orange marbles, If a marble is picked at random, then the probability that it is not an orange marble is

(a) $\frac{1}{4}$

(b) $\frac{1}{3}$

(C) $\frac{4}{9}$

 

(d) $\frac{7}{9}$

Solution:

GIVEN: A bag contains 3green, 4blue and 2orange marbles

TO FIND: Probability of not getting an orange marble

Total number of balls 3+4+2=9

Total number of non orange marbles that is green and blue balls is

We know that PROBABILITY = 

Hence probability of getting a non orange ball is 

Hence the correct option is
