A toy box contains eight green balls and four purple balls. Suppose you choose a ball at random and then replace it by putting i
dedylja [7]

Answer: C.  \dfrac{1}{3}

Step-by-step explanation:

Given: Box contains 8 green balls and 4 purple balls.

Total balls = 8+4 = 12

event 1 = first picking green ball

event 2 = second picking purple balls.

As first ball was replaced, that means both events are independent.

Probability that you have selected a green ball and then a purple ball = P(purple ball )

Formula for probability = \dfrac{\text{favorable outcomes}}{\text{total outcomes}}

Probability of selecting a purple ball (second pick)= \dfrac{4}{12}

=\dfrac{1}{3}

The required probability =\dfrac{1}{3}, so C is correct option.
