Step-by-step explanation:
GIVEN: An urn contains green and pink balls. Four balls are randomly drawn from the urn in succession, with replacement. That is, after each draw, the selected ball is returned to the urn.
TO FIND: What is the probability that all 4 balls drawn from the urn are pink.
SOLUTION:
Total balls in urn
Total green balls
Total pink balls
probability of getting a pink ball
As selected ball is returned to the urn, therefore drawing a ball is an independent event.
probability of getting all balls pink
Hence the probability that all 4 balls drawn from the urn are pink is
You would need 30/12 boxes, which simplifies down to 2 and 6/12 boxes, which further simplifies to 2 1/2 boxes.
