Question

A bag contains red and blue balls totaling 12. If the probability of taking out a red ball randomly from the bag is 1/3 then find the number of blue balls in the bag.

Answer 1

Answer:

8

Step-by-step explanation:

Let the number of red balls be 'r'.

Therefore, the number of blue balls is '12-r'.

From the statement above,

r/12 = 1/3

3r/12 = 1

r = 4

Hence, the number of red balls is 4.

The number of blue balls is;

12-r

= 12-4

= 8

Hence the number of blue balls in the bag is 8.
