Question
From a bag of 2 red, 3 blue and 2 black balls. A ball is picked out at random. The probability to get red ball is_______
Hint:
We have to find the probability of getting red ball if randomly picked from a bag which has 2 red balls, 3 blue balls and 2 black ball. First we will find the total number outcomes which will be the total number of balls in this case. Then we will find the number of possible outcome which will the number of red balls. Further we will find the probability by dividing no. of possible outcomes by total no. of outcomes.
The correct answer is:
Total no. of total outcome = 2+3+2=7
No. of possible outcome ( no. of red balls)= 2
Possibility=
So, probability of getting red ball is .
