40% of oatypop cereal boxes contain a prize. hannah plans to keep buying cereal until she gets a prize. what is the probability that hannah only to buy 3 or less boxes before getti g a prize? we need to design a simulation. which random can we use to best represent this situation

The percent probability of winning a prize=40%.

and not winning prize=60%.

We are asked to find the probability that Hannah only has to buy 3 or less boxes before getting a prize.

Let the random used is x=0,1,2,3  ( where

Hence, the probability that the first box will contain prize=

The probability that the first box will not contain prize but second will=

The probability that the first  and second box will not contain prize but third will=

The probability that the first  and second box will not contain prize but third will=

The probability that the prize is not contained in first, second and third box=

Hence, the total probability=
