There are 5.1090942e+19 different ways this test can be completed
<h3>In how many different ways can this test be completed?</h3>
The given parameters are:
Questions, n =21
Options = 2 i.e. true or false
The number of different ways this test can be completed is calculated as:
Ways = n!
Substitute 21 for n in the above equation.
So, we have:
Ways = 21!
Expand the above equation
Ways = 21 * 20 * 19 * ...... 1
Evaluate the products
Ways = 5.1090942e+19
Hence, there are 5.1090942e+19 different ways this test can be completed
