Six balls numbered 1 to 6 are placed in a bag. Some of the balls are grey and some are white. The balls numbered 2 and 5 are grey. The balls numbered 1, 3, 4, and 6 are white.

A ball will be selected from the bag at random. The 6 possible outcomes are listed below. Note that each outcome has the same probability.

Visual Diagram:
- Number 1: white
- Number 2: grey
- Number 3: white
- Number 4: white
- Number 5: grey
- Number 6: white

Complete parts (a) through (c). Write the probabilities as fractions.

(a) Check the outcomes for each event below. Then, enter the probability of the event.

| Event | Description | Outcomes (1, 2, 3, 4, 5, 6) | Probability |
|-------|-------------|-----------------------------|-------------|
| Event A | The selected ball is white  | □ □ □ □ □ □ |      |
| Event B | The selected ball has an even number on it | □ □ □ □ □ □ |      |
| Event A and B | The selected ball is white and has an even number on it | □ □ □ □ □ □ |      |
| Event A or B | The selected ball is white or has an even number on it  | □ □ □ □ □ □ |      |

### Probability Exercise Description

This exercise involves calculating probabilities based on different events related to selecting a ball from a set. The events are defined as follows:

- **Event B:** The selected ball has an even number on it.
- **Event A and B:** The selected ball is white *and* has an even number on it.
- **Event A or B:** The selected ball is white *or* has an even number on it.

### Task Instructions

1. **Compute the Following:**

   The task is to solve the equation for the combined probabilities as given:

   \[
   P(A) + P(B) - P(A \text{ and } B) = \Box
   \]

   An empty box is provided for the answer.

2. **Select the Correct Answer:**

   You need to choose the answer that makes the equation true:

   \[
   P(A) + P(B) - P(A \text{ and } B) = (\text{Choose one}) \, \Box
   \]

   A dropdown menu is given to select the appropriate value.

### Diagram Explanation

The diagram in this exercise consists of icons representing different configurations of the events. Checkboxes are provided to select or mark the condition that satisfies the event descriptions.
