Lucia flips a coin three times. What is the probability she gets (Head, tail, Head) in that order?

Svetach [21]

Answer: $\dfrac{1}{8}$

Step-by-step explanation:

The total outcomes of tossing a coin = 2

The total number of possible outcomes of flipping coin three times =2 x 2 x 2 = 8

Favorable outcome= (Head, tail, Head) in order

i.e. Number of Favorable outcomes = 1

We know that , Probability = $\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

Therefore , The required probability $=\dfrac{1}{8}$

Hence , the probability she gets (Head, tail, Head) in that order $=\dfrac{1}{8}$
