excel選択してランダム化

Question

私はまだこれを理解しようとしています。私はこのデータをExcelの1つのシートに入れています。

City   Risk Level 
Facility 1 Extremely Low Risk 
Facility 2 Very High Risk 
Facility 3 Very Low Risk 
Facility 4  Low Risk 
Facility 5 Moderate Risk 
Facility 6 Moderate Risk 
Facility 7  High Risk 
Facility 8  Extremely Low Risk 
Facility 9  Very Low Risk 
Facility 10  Low Risk 
Facility 11 Moderate Risk 
Facility 12 Extremely Low Risk 
Facility 13  Very High Risk 
Facility 14  Very Low Risk 
Facility 15  Low Risk 
Facility 16  Moderate Risk 
Facility 17  Highly Moderate Risk 
Facility 18  High Risk 
Facility 19  Extremely Low Risk 
Facility 20  Very Low Risk 
Facility 21  Low Risk 
Facility 22  Moderate Risk 
Facility 23  Highly Moderate Risk 
Facility 24  High Risk 
Facility 25  Very High Risk 
Facility 26  Extremely Low Risk 
Facility 27  Very Low Risk 
Facility 28   Low Risk 
Facility 29  Moderate Risk 

Risk Levels   Desired 
Extremely Low Risk  3 
Very Low Risk   4 
Low Risk    4 
Moderate Risk   5 
Highly Moderate Risk 2 
High Risk    2 
Very High Risk   1 

それぞれのリスクレベルから希望する施設の数を選択できるフォーミュラがあるかどうかを知りたいと思います。例：「非常に低いリスク」の3つの施設、「非常に低いリスク」の4つの施設、「低リスク」の4つの施設、「中程度のリスク」を伴う5つの施設など...施設を選びたい私は施設の名前を列ではなく行に表示したいと思っています。

どうすればいいのか教えてください。

ありがとうございます。

あなたはこの式を使用することができます

=IF(COLUMN(A:A)<=$E2,INDEX($A:$A,AGGREGATE(15,6,ROW($B$2:$B$30)/(($B$2:$B$30=$D2)*(COUNTIF($E$2:E2,$A$2:$A$30)=0)),RANDBETWEEN(1,COUNTIF($B$2:$B$30,$D2)-COLUMN(A:A)+1))),"")
