Question

A man kill a bird once in three shots. The probability that a bird is not killed is -

• A. $\frac{1}{3}$
• B. $\frac{2}{3}$
• C. $1$
• D. $0$

Answer 1

The correct option is B $\frac{2}{3}$

A man kill a bird once in three shots. The probability that a bird is killed is

$P\left(E\right)=\frac{1}{3}$

Therefore The probability that a bird not is killed is

$P\left(E^{\prime }\right)=1-P\left(E\right)=1-\frac{1}{3}=\frac{2}{3}$.
