The problem involves selecting a tile from seven tiles, each labeled with a different letter from the first seven letters of the alphabet: **A, B, C, D, E, F, G**. 

### Definitions:
- **Event X**: The letter selected comes before "D" (i.e., **A, B, C**).
- **Event Y**: The letter selected is found in the word "CAGE" (i.e., **C, A, G, E**).

We need to determine the outcomes for the following:

### (a) Event "X and Y"
The intersection of **X** and **Y** is the set of letters that are both before "D" and in "CAGE". This means:
- **X** (letters before "D") = {A, B, C}
- **Y** (letters in "CAGE") = {C, A, G, E}

The common letters in both sets are **A** and **C**. Therefore:
- Event "X and Y" = {**A, C**}.

### (b) Event "X or Y"
This is the union of **X** and **Y**, which means all letters that are either in **X** or in **Y**. The union of the two sets is:
- **X** (letters before "D") = {A, B, C}
- **Y** (letters in "CAGE") = {C, A, G, E}

The union is **{A, B, C, G, E}**. Therefore:
- Event "X or Y" = {**A, B, C, G, E**}.

### (c) The complement of Event Y
The complement of **Y** includes all letters that are not in **Y** (i.e., not in "CAGE"). The full set of letters is **{A, B, C, D, E, F, G}**, and **Y** = {C, A, G, E}. Therefore, the complement of **Y** includes the letters that are not in **Y**:
- The complement of **Y** = **{B, D, F}**.

### Final answers:
- **(a)** Event "X and Y" = **{A, C}**
- **(b)** Event "X or Y" = **{A, B, C, G, E}**
- **(c)** Complement of event Y = **{B, D, F}**

### Tip:
When solving probability problems, organizing outcomes into sets and using Venn diagrams can help visualize intersections and unions easily.

A tile is selected from seven tiles, each labeled with a different letter from the first seven letters of the alphabet. The letter selected will be recorded as the outcome. Event X: The letter selected comes before 'D'. Event Y: The letter selected is found in the word 'CAGE'. Give the outcomes for each of the following events: (a) Event 'X and Y', (b) Event 'X or Y', (c) The complement of the event Y.
