Question

In a box, there are 6 red, 7 blue and 8 green balls. One ball is picked up randomly. The probability that the ball drawn is neither red nor blue is_____.

  1. 12 over 2
  2. 8 over 21
  3. 11 over 4
  4. 10 over 5

hintHint:

We have to find the probability that the ball is neither red nor blue. First we will find the number of total number of outcomes. Then we will find the number of possible outcomes i.e. neither red nor blue. Further we will find the probability by dividing number of possible outcomes by total number outcome.

The correct answer is: 8 over 21


    Total no. of outcomes = 6+7+8 = 21
    no. of possible outcomes(neither red nor blue i.e. green) = 8
    Possibility =8 over 21
    so, the probability that ball is neither red nor blue is 8 over 21.
