Question

6. A bag contanis 3 red balls, 5 black balls and 4
white balls. Aball is drawn at random from the
bag. What is the probability that the ball
drawn is not red ?

Answer 1

Answer:

total balls=12

p(ball is not red)=9\12

Answer 2

Step-by-step explanation:

Total number of balls present in the bag = 12

number of red balls = 3

therefore, probability of the red ball to come out = 3/12

=1/4

number of black balls = 5

therefore, probability of the black ball to come out =5/12

again ,

number of white balls = 4

therefore, probability of black colour ball to come out = 4/12

= 1/3

the probability that the ball is not read is= 9/12
