A bag contains a black ball, a red ball and a green ball, all the balls are identical in shape and size. … (ii) not a red ball (iii)…
Answers:
Total number of possible outcomes = 3
∴ P(E) = 1/3
(ii) Not a red ball
Number of favourable outcomes = Green ball + Black ball
= 1 + 1 + 2
∴ P(E) = 2/3
(iii) A white ball
Number of favourable outcomes = 0
∴ P(E) = 0/3 = 0
