Two coins are tossed. Find the probability that one coin is a head and the other is a tail.
The ratio between the number of favorable outcomes to the total number of outcomes is called probability. It lies between 0 and 1.
Answer: The probability that one coin is a head and the other is a tail is 1/ 2.
Let's find the probability.
Let H be the head and T be the tail.
When two coins are tossed, the sample space outcomes will be
(H, H), (H, T), (T, H), (T, T)
We have two outcomes where one coin is head and another is tail.
⇒ P(E) = Number of favorable outcomes / Total number of outcomes.
⇒ P (getting one head and one tail) = 2 / 4 = 1 / 2
