Question

A bag contains 18 balls out of which x balls are red if one ball is drawn out random from the bag what is the proabability that it is not red

Answer 1

Answer:

(18-x)/18

Step-by-step explanation:

Total balls = 18

No. of red balls = x

So,

No. of non-red balls = 18 - x

F(e) = Favoured Events (No. of Non-Red Balls) = 18-x

T(e) = Total Events (Total Balls) = 18

So,

P = Probability = F(e)/T(e) = [(18-x)/18] - Ans.
