Q.1 A bag contains four black and five red balls, if three balls are picked at random one after another WITH replacement, what is the chance that they’re all black? A) 64/729 B) 64/730 C) 63/729 D) 63/730 Ans. A With replacement means you pick up a ball note down its color and then put it back in the bag again. So Total Number of balls remain same for each event. And Hence probability of picking a black ball (4/9) remains the same in every case. 1st Pick up:4/9; 2nd Pick up: 4/9 ;because we put the ball back in the bag, So probability is same as “1st Pick”. 3rd Pick up: 4/9 ;because we put the ball back in the bag. So final probability =1st x 2nd x 3rd =4/9 x 4/9 x 4/9 =Cube of 4/9 =64/729 Q.2 If you have a spinning wheel with 3 green sectors, 1 blue sector and 1 red sector, what is the probability of getting a green sector? What is the probability of getting a non blue sector? A) Green = 3/5 ; Non-blue = 4/5 B) Green = 2/5 ; Non-blue = 3/5 C) Green = 4/5 ; Non-blue = 3/5 D) Green = 3/5 ; Non-blue = 2/5 Ans. A Total number of events = 5 Q.3 A bag has 4 red balls and 2 yellow balls. (The balls are identical in all respects other than colour). A ball is drawn from the bag without looking into the bag. What is probability of getting a red ball? A) 2/3 B) 2/4 C) 2/5 D) 2/6 Ans. A There are in all (4 + 2 =) 6 outcomes of the event. Getting a red ball consists of 4 outcomes. Therefore, the probability of getting a red ball is 4/6 = 2/3 Q.4 There are 100 students in a particular class. 60% students play cricket, 30% student play football and 10% students play both the games. What is the number of students who play neither cricket nor football? A) 25 B) 20 C) 18 D) 15 Ans. B 100- (50+20+10) = 100-80 = 20 Q.5 In a group of persons, 70% of the persons are male and 30% of the persons are married. If two-sevenths of the males are married, what fraction of the females is single? A) 2/7 B) 1/3 C) 3/7 D) 2/3 Ans. D Let total no. of persons =100 Therefore total no. of males= 70 Total no. of females= 30 Given that, no. of unmarried persons =30 So, Number of married males= 2/7 * 70=20 Therefore, No. of married females =30-20 =10 Therefore, No. of unmarried females =30-10 = 20 Therefore, Required fraction of single females= 20/30 = 2/3
