Example 1 :There are 4 red balls and 3 green balls in a bag. One ball is taken out at random.What is the probability of getting a red ball ?
Total no.of balls = 4+3 = 7 Favourable balls = 4 (as there are 4 red balls ) Required Probability = Total no. of fav. balls /Total no. of balls = 4/7 Example 2.What is the probability of not getting a red ball ? Total no.of balls = 4+3 = 7 Favourable balls = 3 (as there are 3 balls other than red balls ) Required Probability = Total no. of fav. balls /Total no. of balls = 3/7 Example 3 :There are 4 red balls , 5 blue balls and 3 green balls in a bag. One ball is taken out at random.What is the probability of getting a red ball ? Total no.of balls = 4+5+3 = 12 Favourable balls = 4 (as there are 4 red balls ) Required Probability = Total no. of fav. balls /Total no. of balls = 4/12=1/3 Example 4. What is the probability of not getting a red ball ? Total no.of balls = 4+5+3 = 12Favourable balls = 8 (as there are 8 balls other than red balls )Required Probability = Total no. of fav. balls /Total no. of balls = 8/12 =2/3 Example 5. What is the probability of not getting a red or a green ball ? Total no.of balls = 4+5+3 = 12 Favourable balls = 9 (as there are 4 red balls and 5 green balls ) Required Probability = Total no. of fav. balls /Total no. of balls = 9/12 =3/4 For more solved questions Visit: http://jsuniltutorial.weebly.com/probability.html Practice Test paper 1. Two dice are thrown once. What is the probability of getting a doublet? 2. A jar contains 54 marbles of colour blue, green and white.
