Three coins are tossed once. Let A denote the event ‘three heads snow”, B denote the event “two heads and one tail show”, C denote the event” three tails show and D denote the event 'a head shows on the first coin”. Which events are(i) mutually exclusive?     (ii) simple?     (iii) Compound?

Explanation

To solve the problem, we will analyze the events defined and determine which are mutually exclusive, simple, and compound.

### Step-by-Step Solution:

1. **Identify the Sample Space**:
When three coins are tossed, the sample space (S) consists of all possible outcomes. The outcomes are:
- HHH (three heads)
- HHT (two heads, one tail)
