• question_answer If the probability of hitting a target by a shooter, in any shot, is $\frac{1}{3},$ then the minimum number of independent shots at the target required by him so that the probability of hitting the target at least once is greater than $\frac{5}{6}$ is: A) $3$ B) $6$ C) $5$ D) $4$

 $1-{{\left( \frac{2}{3} \right)}^{n}}>\frac{5}{6}$ ${{\left( \frac{2}{3} \right)}^{n}}<\frac{1}{6}$ $\Rightarrow$  $n=5.$
