The probability that a man failing to hit a target is \(\frac{1}{3} \cdot\) If he fires 4 times, then the probability that he hits the target at least thrice is
- A \(\frac{16}{27}\)
- B \(\frac{11}{27}\)
- C \(\frac{8}{81}\)
- D \(\frac{32}{81}\)
Answer & Solution
Correct Answer
(A) \(\frac{16}{27}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{q}=\mathrm{P}(\) failing to hit a target \()=\frac{1}{3}\) \(\Rightarrow \mathrm{P}=1-\frac{1}{3}=\frac{2}{3}\) and \(n=4\) P (hits the target at least thrice)…
