Bag Contains Black Ball Red Ball And Green Ball All Balls Are Identical In Shape And Size

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
