Question

A coin is tossed $100$ times with following frequency.
Head: $25$, Tail: $75$. Find the probability of getting a tail?

• A. $\frac{1}{2}$
• B. $\frac{1}{3}$
• C. $\frac{1}{4}$
• D. $\frac{3}{4}$

Answer 1

The correct option is D $\frac{3}{4}$

Frequency of heads $=25$

Total number of trials $=100$

$P\left(T\right)=\frac{\text{No. of tail}}{\text{Total number of trials}}=\frac{75}{100}=\frac{3}{4}$
