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
คำอธิบาย
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.
