Probability
The probability of getting a head when a fair coin is tossed is
Select the correct option:
Solution
1/2
- Sample Space (S): When a coin is tossed, S={H,T}. Total outcomes n(S)=2.
- Event (E): Getting a Head. E={H}. Favorable outcomes n(E)=1.
- Formula: P(E)=n(S)n(E).
- Result: P(H)=1/2.
- Constraint: The term 'fair' implies that both outcomes are equally likely.
