A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).
The 2 and + are out since they don't have variables(and the + is just a +).
So 4 and x are left. x is a variable, not a coefficient, so the last(and correct) answer is 4.

The order in which the two players will be selected from the 8 trying players is not important. The most important thing is to have the two players.
Therefore, this is a question of combination.
The number of groups = 8C2 = 8!/[2!*(8-2)!] = (8*7*6*5*4*3*2*1)/[(2*1)*(6*5*4*3*2*1)] = 28 groups
The mixed number as an improper fraction is 37/8
<h3>How to express the mixed number as an improper fraction?</h3>
The diameter is give as:
Diameter = 4 5/8
Next we convert the above number to an improper fraction
The numerator is calculated as
Numerator = 8 * 4 + 5
This gives
Numerator = 37
Hence, the mixed number as an improper fraction is 37/8
