Questions and formulas:
Question: What is the total launch failures when there are 4 launches, and the not usable is greater than 0?
Formula: SUM(FILTER(F1, (B1=4)*(D1>0)))
Formula2: SUM(FILTER(F2:F8, (B2:B8=4)*(D2:D8>0)))
Level: easy
Question: What is the highest number of not usable satellites when there are more than 0 launch failures, less than 30 retired, and the block is I?
Formula: MAX(FILTER(D1, (F1>0)*(E1<30)*(A1="block i")))
Formula2: MAX(FILTER(D2:D8, (F2:F8>0)*(E2:E8<30)*(A2:A8="block i")))
Level: easy
Question: What is the average number of not usable satellited when there are 0 retired, and the launch failures are less than 1?
Formula: AVERAGE(FILTER(D1, (E1=0)*(F1<1)))
Formula2: AVERAGE(FILTER(D2:D8, (E2:E8=0)*(F2:F8<1)))
