A jar contains 11 red marbles, 12 blue marbles, and 6 white marbles. Four marbles from this jar are selected, with each marble b
eing replaced after each selection. What is the probability that at least 1 of the selected marbles is blue? (StartFraction 12 Over 29 EndFraction) Superscript 4
(StartFraction 17 Over 29 EndFraction) Superscript 4
1 minus (StartFraction 12 Over 29 EndFraction) Superscript 4
1 minus (StartFraction 17 Over 29 EndFraction) Superscript 44
This is because you need to figure out the probability that a selected marble is not blue, which is (17/29)^4. Then you can calculate the probability that one of them is blue by taking this number, and subtracting it from 1. This results in 1-(17/29)^4.
