Answer:
Probability of all 4 balls drawn should be green equal to ≈ .
Step-by-step explanation:
Given that,
An urn contains 6 green and 5 pink balls.
Now, Total number of balls in urn is balls.
Four balls are randomly drawn from the urn in succession, with replacement.
So, probability of green ball =
Again, there is a condition that,
Probability all 4 balls drawn should be green.
Then, P(all 4 balls should be green)=
=
=
≈
Therefore,
Probability of all 4 balls drawn should be green equal to ≈ .
