Question

A coin is tossed five times, find the probability of getting $4$ heads.

• A. $\frac{5}{32}$
• B. $\frac{1}{32}$
• C. $0.4$
• D. $0.25$

Answer 1

The correct option is A $\frac{5}{32}$

Given: Coin tossed $5$ times

To find the probability of getting $4$ heads

According to the question:

$n\left(S\right)=2^5=32$

Favourable outcomes for getting $4$ heads are $\{HHHHT,HHHTH,HHTHH,HTHHH,THHHH\}=5$

Hence, the probability of getting $4$ heads is

$=\frac{5}{32}$
