Question

a bag contains 8 red ,10 white and 12 blue marbles. if a marble is drawn from the bag at random find the probabilty that the ball drawn is (¡)blue (¡¡) red
​

Answer 1

Step-by-step explanation:

Total balls = 8 + 10 + 12 = 30 balls

A random marble is drawn

probability that the ball is blue = 12 / 30

= 2 / 5

probability that the ball is red = 8 / 30

= 4/ 15

Answer 2

Step-by-step explanation:

probability = favourable number of outcome / total number of outcome

p( blue) = 12/30

= 2/5

p(blue) = 2/5 Ans

p(red) = 8 /30

p( red) = 4/15 Ans
