A coin is tossed once. The probability of getting heads is

A0
B1/4
C1
D1/2
Answer & Solution
Correct answer: D. 1/2
1. Sample space S = {H, T} has 2 equally likely outcomes. 2. Favourable outcomes (heads) = {H}, count 1. 3. P(H) = favourable / total = 1/2. 4. So the probability of heads is 1/2. _Source: ICAI BoS Foundation Paper 3, Ch 15 'Probability', p.4_
