Given
A bag contains 25 marbles,
12 red
8 blue
5 green
To find the probability of pulling 3 green marbles out of a bag with replacement.
Explanation:
It is given that,
A bag contains 25 marbles,
12 red
8 blue
5 green.
That implies,
The probability of getting 3 green balls is,
[tex]\begin{gathered} P(getting\text{ }3\text{ }green\text{ }marbles)=\frac{5}{25}\times\frac{5}{25}\times\frac{5}{25} \\ =\frac{1}{125} \end{gathered}[/tex]Hence, the probability of getting 3 green balls with a replacement is 1/125.
