One out of 9 ships is likely to sink when they are set on sail. When 6 ships are set on sail, the probability that exactly 3 of them will not arrive safely is:
In a test, a student either guesses, copies, or knows the answer to a multiple-choice question with four choices. The probability that he makes a guess is \( \frac{1}{3} \), and the probability that he copies is \( \frac{1}{6} \). The probability that his answer is correct, given that he guessed it, is \( \frac{1}{4} \), and the probability that he copied it and it is correct is \( \frac{1}{8} \). The probability that he knew the answer to the question, given that he answered it correctly, is:
An analysis of monthly wages paid to the workers of two jute mills A and B gives the following data:
\begin{tabular}{|c|c|c|} \hline & Mill - A & Mill - B
\hline No. of workers & 500 & 600
Average daily wage (in rupees) & 186 & 175
Variance of distribution of wages & 81 & 100
\hline \end{tabular} Then:
