Compute the relative frequency of the given event if an author as specified is chosen at random.
A new author is unsuccessful.

Expert Solution

Solution:

The relative frequency of an event is the number of times an event occurs, divided by the total number of trials.

That is, $P (A) = \frac{F r e q u e n c y o f E v e n t A}{N u m b e r o f T r i a l s}$

The event A is that a new author is chosen who is unsuccessful.

The number of times this event occurs is 64.

The total number of trials are 400.
