The probability of getting a success in a trail is five times that of a failure. The probability of getting at most one success in 5 trails, is
- A \(\frac{25}{6^5}\)
- B \(\frac{26}{6^5}\)
- C \(\left(\frac{5}{6}\right)^5\)
- D \(2\left(\frac{5}{6}\right)^5\)
Answer & Solution
Correct Answer
(B) \(\frac{26}{6^5}\)
Step-by-step Solution
Detailed explanation
Let the probability of success and failure are \(\mathrm{P}\) and \(\mathrm{q}\) respectively then, \(p=5 q\) \[ \frac{\mathrm{P}}{\mathrm{q}}=\frac{5}{1} \] So, \(\mathrm{p}=\frac{5}{6}, \mathrm{q}=\frac{1}{6}\)…
