The probabilities of two persons to hit a target are \(\frac{1}{4}\) and \(\frac{1}{5}\) respectively. The probability that the target is being hit when both of them attempt independently is
- A \(\frac{1}{2}\)
- B \(\frac{3}{5}\)
- C \(\frac{2}{5}\)
- D \(\frac{7}{10}\)
Answer & Solution
Correct Answer
(C) \(\frac{2}{5}\)
Step-by-step Solution
Detailed explanation
Let probabilities of target by two persons are \(\mathrm{P}_1\) and \(\mathrm{P}_2\) respectively. \[ \mathrm{P}_1=\frac{1}{4}, \mathrm{P}_2=\frac{1}{5} \] \(\mathrm{P}\) (both persons do not hit target)…
