Question

An editor has a stack of k documents to review. The order in which the documents are reviewed is random with each ordering being equally likely. Of the k documents to review, two are named “Relaxation Through Mathematics” and “The Joy of Calculus.” Give an expression for each of the probabilities below as a function of k. Simplify your final expression as much as possible so that your answer does not include any expressions in the form a b . (a) What is the probability that “Relaxation Through Mathematics” is first to review?

Answer 1

Using the probability concept, it is found that there is a $\mathbf{\frac{1}{k}}$ probability that “Relaxation Through Mathematics” is first to review.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

• There is a total of k documents to be reviewed, hence $T = k$.
• Of those documents, 1 is named “Relaxation Through Mathematics”, hence $D = 1$

The probability is:

$p = \frac{D}{T} = \frac{1}{k}$
