Question

A bag contains six identical black balls. A child withdraws one ball from the bag without looking into it. What is the probability that he takes out a black ball?

Answer 1

Possible number of outcomes = 6 = number of balls in the bag 

n(S) = 6 

E = event of drawing a black ball = number of black balls in the bag = 6

n(E) = 6 

Probability of drawing a black ball = P(S)

= `(n(E))/(n(S))`

= `6/6`

= 1
