Chapter 8, Problem 80RE

To determine

To calculate:

The number of possible system configurations

Answer to Problem 80RE

The number of possible system configurations is $180ways$ .

Explanation of Solution

Given information:

Three events:

One of five DVD players

One of six flat screen televisions

One of six speaker systems

Formula used:

The fundamental counting principal is given as:

  $N=n\times m$

Where,

The number of ways of doing something: $n$

The number of ways of doing another thing: $m$

Calculation:

There are three events are given in the given problem as:

One of five DVD players: $5ways$

One of six flat screen televisions: $6ways$

One of six speaker systems: $6ways$

Now, by using fundamental counting principal, the number of possible system configurations is estimated as:

  $\begin{array}{l}N=5\times 6\times 6\\ N=180\end{array}$

So, there are $180ways$ can be used for the system configurations.
