  #### A bag contains 10 red, 5 blue and 7 green balls. A ball is drawn at random. Find the probability of this ball being a(i) red ball (ii) green ball (iii) not a blue ball Solution. Probability; Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Total balls = 10 + 5 + 7 = 22
Red balls = 10
Probability =
Probability of getting red ball =

Solution.   Probability; Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one

Total balls = 10 + 5 + 7 = 22
Green balls = 7
Probability =
Probability of getting green ball =

Solution. Probability; Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Total balls = 10 + 5 + 7 = 22
Not a blue ball = 22  – (blue ball)
= 22 – 5 = 17
robability =
Probability of getting not a blue ball =
