We are given that A fair coin is tossed 5 times and we need to find What is the probability that the fourth toss would turn a head

Whenever we are given a fair coin then the probability of getting a head or a tail at any stage will always be equal to $$\frac{1}{2}$$

This number changes only when we are asked for something like, what is the probability of getting 3 heads in 6 tosses etc. But at each and every stage of the toss, provided it is a fair coin, the probability of getting a head or tail will always be = $$\frac{1}{2}$$
