Mathematics for IGCSE & O level - Probability (Section 2 - No. 17)
When tossing a coin twice, what is the probability of getting a head followed by a tail? (Assume fair coin)
1/4
1/2
1/8
3/4
Explicación
The probability of getting a head is 1/2, and the probability of getting a tail is 1/2. Since the events are independent, the probability of both happening is (1/2) * (1/2) = 1/4.
