A bag contains 5 white and 7 red balls. One ball is drawn at random. What is the probability that ball drawn is white?

Answer:

Total numbers of red balls = 7 Number of white balls = 5

Total number of Non red balls = 7 + 5 = 12

Probability of getting a non-white ball is = Total number of non-white balls/Total number of balls

= 5/12

∴ Probability of getting a non-white ball is 5/12
