Question

A person can kill a bird with probability$3/4$. He tries $5$times. What is the probability that he may not kill the bird

• A. $243/1024$
• B. $781/1024$
• C. $1/1024$
• D. $1023/1024$

Answer 1

The correct option is C

$1/1024$

Explanation for the correct option:

Calculate the probability :

Given that, the probability that the person can kill the bird $=3/4$

The probability that the person cannot kill the bird $=1-\frac{3}{4}=\frac{1}{4}$

Since he tries five times.

Thus, the probability that he may not kill the bird $={\left(\frac{1}{4}\right)}^5=\frac{1}{1024}$

Hence the correct option is C.
