Answer 1

To determine the probability of selecting a 4 given that a green disk is selected, we need to know how many of the disks are green and how many of those green disks are numbered 4. However, as the colors of the disks are not provided in your question, I can only explain the method to find the solution.

The probability can be calculated using the formula for conditional probability:

\[
P(A|B) = \frac{P(A \cap B)}{P(B)}
\]

Where:
- \(P(A|B)\) is the probability of event A (selecting a 4) given event B (selecting a green disk).
- \(P(A \cap B)\) is the probability of both A and B occurring (selecting a green disk that is also numbered 4).
- \(P(B)\) is the probability of event B occurring (selecting any green disk).

You will need to provide how many green disks are present and which of them, if any, is numbered 4, in order to find the specific probabilities.

If you have this information, please share it so that I can assist you with the calculations!
