Question

The probability that a person will hit a target in shooting practice is $0.3$. If he shoots $10$ times, then the probability of his shooting the target is

• A. $1$
• B. $1-{\left(0.7\right)}^{10}$
• C. ${\left(0.7\right)}^{10}$
• D. ${\left(0.3\right)}^{10}$

Answer 1

The correct option is B $1-{\left(0.7\right)}^{10}$

The probability that a person will hit a target in shooting practice is $0.3$

$\therefore$ The probability that the person does not hit the target $=1-0.3=0.7$
$\therefore$ Probability of not shooting the target $={\left(0.7\right)}^{10}$
$\therefore$ Probability of shooting the target $=1-{\left(0.7\right)}^{10}$
