Question

A fair coin is tossed repeatedly. If the tail appears on first four tosses, then the probability of the head appearing on the fifth toss equals:

• A. $1/2$
• B. $1/32$
• C. $31/32$
• D. $1/5$

Answer 1

The correct option is A $1/2$

For a fair coin
$P\left(head\right)=P\left(tails\right)=\frac{1}{2}$
Hence it will remain the same, and the answer to the above question is $\frac{1}{2}$.
