Basically, what you're describing here for your desired result is the =AVERAGEA() function

_{The Microsoft Excel AVERAGEA function returns the average (arithmetic mean) of the numbers provided. The AVERAGEA function is different from the AVERAGE function in that it treats TRUE as a value of 1 and FALSE as a value of 0.}

With that in mind, the formula should look like this.

=SUM(AVERAGEA(A1:A4),AVERAGEA(B1:B4),AVERAGE(C1:C4),AVERAGEA(D1:D4),AVERAGEA(E1:E4))

Produces the expected result:

Note, if you want to ROUND() the result to two digits, add the following formula to it:

=ROUND(SUM(AVERAGEA(A1:A4),AVERAGEA(B1:B4),AVERAGE(C1:C4),AVERAGEA(D1:D4),AVERAGEA(E1:E4)), 2)
