Answer:

756 ways

Step-by-step explanation:

Given

[tex]Counters = 28[/tex]

[tex]Selection = 2[/tex]

Required

Determine the number of ways

The first counter can be selected in 28 ways

The second can be selected in (28 - 1) ways

The number of selection is:

[tex]Selection = 28 * (28 -1)[/tex]

[tex]Selection = 28 * 27[/tex]

[tex]Selection = 756[/tex]

Hence, number of possible selection is 756
