Step1: Recall average formula

The average (arithmetic - mean) of a set of numbers is given by $\text{Average}=\frac{\text{Sum of numbers}}{\text{Number of numbers}}$.

Step2: Calculate sum of scores

The scores are 167, 178, and 186. The sum is $167 + 178+186=531$.

There are 3 scores. So the average is $\frac{531}{3}=177$.
