Question

In a box there are 6 blue ball, X red balls & 10

green balls. Probability of choosing one red

ball from the given box is 1/3, then find the

sum of red and blue balls in the box?​

Answer 1

Answer:

Total balls= 6 + x +10 = x + 16

Probabiliy of red ball = x/(x + 16)

or 1/3 = x/(x + 16)

or 3x = x + 16

or 2x = 16

or x= 8

So, no of red balls = 8

Sum of red and blue balls = 6 + 8 = 14

Answer: 14 balls
