Given: A coin is tossed 3 times.

To find: Probability of getting head and tails alternatively.

________________________________

.

A coin is tossed 3 times

⇒ Total no of Outcomes = 2³ = 8

Sample Space or All Outcomes = {(H,H,H) , (H,H,T) , (H,T,H), (H,T,T), (T,H,H), (T,H,T), (T,T,H), (T,T,T)}

Here H for head & T for Tail.

Thus, Favorable outcomes are = { (H,T,H) , (T,H,T) }

【Probability = 2/8 = 1/4.】

Therefore, Probability of getting Head & Tail alternatively is 1/4.
