Bag Contains Six Identical Black Balls

A bag contains six identical black balls. A child withdraws one ball from the bag without looking into it. … (i) a white ball, (ii) a…


∵ There are 6 black balls in a bag
∴ number of possible outcome = 6
(i) A white ball
As there is no white ball in the bag
∴ Its probability is zero (0) = or P(E) = 0
(ii) a black ball
∴ Number of favourable outcome = 1

∴ P(E) = Number of favourable outcome/Number of all possible outcome

= 1/6
