Question

A coin is tossed $100$ times with following frequency:
Head: $25$, Tail: $75$

Find the probability of not getting a head.

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

Answer 1

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

Number of times coin is tossed $=1000$

Number of times head doesn't come up (i.e tails comes up)$=100-25=75$

Probability of not getting head $=\frac{75}{100}=\frac{3}{4}$

hence, option $D$ is correct.
