A coin is tossed four times, if H = head and T = tail, what is the probability of the tosses coming up in the order HHTH?

Question: A coin is tossed four times, if H = head and T = tail, what is the probability of the tosses coming up in the order HHTH?

Solution:
Here, Coin is tossed four times.
The total possible outcomes = 16
Outcome = {HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT, TTHH, TTHT, TTTH, TTTT}

Favourable outcome = 1 [HHTH]
∴ Probability = 1/16
