In a university campus, the probability that a person chosen at random is an engineering students is \(\frac{1}{5}\). The probability of having atmost two engineering students in a sample of 8 people is
- A \(45 \times \frac{4^6}{5^8}\)
- B \(17 \times \frac{4^7}{5^8}\)
- C \(27 \times \frac{4^6}{5^8}\)
- D \(19 \times \frac{4^7}{5^8}\)
Answer & Solution
Correct Answer
(D) \(19 \times \frac{4^7}{5^8}\)
Step-by-step Solution
Detailed explanation
Given, chosen person is an engineering student having probability is \(\frac{1}{5}\). In sample of 8 student, for at most two students are engineering students there may be none of students are engineer on only one is engineer or only 2 is engineer:-…
