Publishing Exercises $37-46$ are based on the following table, which shows the results of a survey of 100 authors by $a$ (fictitious) publishing company: $$ \begin{array}{r|c|c|c} & \begin{array}{c} \text { New } \\ \text { Authors } \end{array} & \begin{array}{c} \text { Established } \\ \text { Authors } \end{array} & \text { Total } \\ \hline \text { Successful } & 5 & 25 & 30 \\ \hline \text { Unsuccessful } & 15 & 55 & 70 \\ \hline \text { Total } & 20 & 80 & 100 \\ \hline \end{array} $$Compute the relative frequencies of the given events if $a n$ author as specified is chosen at random. An author is established and successful.
Select correct alternative from the given choices. Eight letters are to be placed in eight addressed envelopes. If the letters are placed at random into the envelopes, the probability that exactly one letter is placed in a wrong addressed envelopes is (A) $\frac{1}{6}$ (B) $\frac{1}{8 !}$ (C) $\frac{1}{7 !}$ (D) None of these
