Question 11.11.Review the partial pseudocode below. Which is the correct math expression to complete the algorithm and calculate the average?
Prompt "Enter first score: "
Input score1
Prompt "Enter second score: "
Input score2
Prompt "Enter third score: "
Input score3
Set _____
Display "Your average is " + avgScore
avgScore = (score1 + score2 + score3) / 2
avgScore = score1 + score2 + score3 / 3
avgScore = (score1 + score2 + score3) / 3
score1 + score2 + score3 / 3 = avgScore
Question 12.12. Review the pseudocode below. Which will be displayed when this algorithm executes?
Set x = 11
If ((x > 10) AND (x < 20)) then
Display "the IF path executes"
Else
Display "the ELSE path executes"
EndIf
the IF path executes
the ELSE path executes
10
(x > 10) AND (x < 20)
