Question

Twenty five coins are tossed simultaneously. The probability that the fifth coin will fall head upwards is

• A. $\frac{5}{2^{25}}$
• B. $\frac{1}{2}$
• C. $\frac{5}{125}$
• D. None of these

Answer 1

The correct option is B $\frac{1}{2}$

since tossing of coin is independent of any tosses then probability of coming H will be same in any toss.
Hence $P\left(Hin5thtoss\right)=\frac{1}{2}$
