Question

Probability of pulling 3 green marbles out of a bag with replacement if there are 25 marbles. 12 red8 blue5 green

Answer 1

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.

Step-by-step 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,

`\begin{gathered} P(getting\text{ }3\text{ }green\text{ }marbles)=(5)/(25)*(5)/(25)*(5)/(25) \\ =(1)/(125) \end{gathered}`

Hence, the probability of getting 3 green balls with a replacement is 1/125.
