one balls drawn without looking
what is chance it is red ?
what is chance it is blue?
what is chance it is green ?​

Answer 1

Answer:

Hey! Here's your answer:

No. of red balls = 10

No. of blue balls = 8

No. of green balls = 12

Total number of balls = 10+12+8 = 30

Now, to find the probability:

P(of an event) = No of favourable outcomes/ total number of outcomes

(i) P(of getting a red ball) = 10/30 = 1/3

(ii) P(of getting a blue ball) = 8/30 = 4/15

(iii) P(of getting a green ball) = 12/30 = 2/5

Hope it helps:)
