A die is thrown. Describe the following events:
`(i)` `A` : a number less than `7`
`(ii) B` : a number greater than `7`
`(iii) C :` a multiple of `3`
`(iv) D`: a number less than `4`
`(v) E` : a even number greater than `4`
`(vi) F` : a number not less than `3`
Also find `AuuB, AnnB, BuuC, EnnF, DnnE, A-C, D-E, EnnF', F'`

Explanation

To solve the problem step by step, we will first define the sample space and then describe each event. After that, we will find the required unions and intersections.

### Step 1: Define the Sample Space
When a die is thrown, the sample space \( S \) is:
\[ S = \{1, 2, 3, 4, 5, 6\} \]

### Step 2: Describe the Events
Now, we will describe each event based on the conditions given:
