To determine the number of students in year 1 and 2 who did not pass, we need to apply two criteria: (1) the student’s Year is 1 or 2, and (2) the Final Grade is below 50. Let’s evaluate each option against these criteria and explain why or why not it would yield the correct count. Option 1: =SUMIFS(C2:C9,"<=2",E2:E9,">50") - This formula uses SUMIFS, which sums values from C2:C9 when the criteria are met. The first criterion "<=2" on the Year column C2:C9 correctly targets years 1 and 2. However, the second criterion is E2:E9, ">50", which selects students whose final grade is greater than 50, i.e., those who passed. Since we want those who did not pass (final grade < 50), this option is counting the opposite group. It is incorrect for the asked question. Option 2: =COUNTIF(C2:C9,"<=2",E2:E9,"<50") - This option attempts to use COUNTIF with two ranges and two criteria. In Excel, COUNTIF supports only a single range and a single criterion. Therefore, this formula is syntactically invalid and would not work as written. It cannot yield the correct count for the described condition. This makes it incorrect. Option 3: =SUMIFS(C2:C9,"<=2",E2:E9,"<50") - Here SUMIFS is used with two criteria, but the function sums values from C2:C9 (the Year column) rather than counting how many rows meet the criteria. Even though the criteria (year <= 2 and final grade < 50) are what we want, summing the Year values does not give the number of students; it would return the total of the year numbers for students meeting the conditions. This is not the desired metric (a count), so it’s incorrect. Option 4: =COUNTIFS(C2:C9,"<3",E2:E9,"<50") - This option uses COUNTIFS with two criteria: C2:C9 "<3" and E2:E9 "<50". The condition "<3" on Year captures years 1 and 2 (since those values are 1 or 2), which is equivalent to asking for year 1 and 2. The second condition "<50" on Final Grade selects those who did not pass. COUNTIFS correctly counts the number of rows that satisfy both criteria, giving the desired count of students in year 1 and 2 who did not pass. This matches the problem’s requirement. In summary, Options 1 and 3 mix the appropriate criteria but misuse the operation (count vs sum) or target the opposite outcome, Option 2 is invalid syntax, and Option 4 correctly counts the rows where Year is 1 or 2 and Final Grade is below 50, producing the correct result.
