Question

A coin is tossed five times, find the probability of getting no tails.

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

Answer 1

Answer: (A)

$\frac{1}{32}$

Given: coin tossed $5$ times

To find: the probability of getting no tails

According to the question:

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

Favourable outcomes for getting no tails is $\left\{HHHHH\right\}=1$

Therefore, the probability of getting no tails is

$\frac{1}{32}$
