Question

If a fair coin is tossed twice, find the probability of getting 'almost one head'.

Answer 1

If a coin is tossed twice, then possible outcomes

{(H, T), (H, H), (T, H), (T, T)}

Total number of outcomes = 4

Number of favourable outcomes = 3

({(T, H), (H, T), (T, T)})

∴ Required probability = `3/4`
