Question

From a bag of 3 red, 3 blue, 4 white balls. A ball is picked at random. The probability to get white ball is_________.

  1. 3 over 4
  2. 3 over 10
  3. 4 over 10
  4. 4 over 7

hintHint:

We have to find the probability of getting white ball if a ball was picked randomly from a bag with 3 red balls, 3 blue balls and 4 white balls. First we will find the total number of outcomes which is the sum of the balls in the bag, then we will find the number of possible outcomes i.e. the number of white balls. Further we will find the probability by dividing number of possible outcomes by total number outcome.

The correct answer is: 4 over 10


    total number of outcomes = 10
    number of possible outcomes ( no. of white balls ) = 4
    Probability = 4/10
    So, the probability of getting white ball is4 over 10.
