(ア) f(x)=x^5+(a)x^4+(b)x^3+(c)x^2+(d)x+(e) (-10≦a,b,c,d≦10,1≦e≦10, a,b,c,d,eは整数)の内，
既約で可解な方程式の個数を SageMath で計算しました．計算時間は約30分でした．
結果は[[a,b,c,d,e], order] の形で出力してます．orderはGalois群Galの位数です.

位数が20の時は Gal=F20, 位数が10の時は Gal=D5,  位数が5 の時は Gal=C5 です．
既約で可解な５次方程式のGalois群はF20,D5,C5の何れかとなります．(参考文献[1][3]) 結果は

F20 238個, D5 449個, C5 10個　計697個．

一方，係数が整数で絶対値が10以下，定数項は正で monicな 5次方程式の個数は
21^4*10=1944810個（約200万個)

故に可解な方程式の割合は
697/1944810=0.00035839(約0.036%)

約3000個に1個の割合でしか，可解な5次方程式と出会うことは有りません!

【重要】f(x)=x^5+(a)x^4+(b)x^3+(c)x^2+(d)x+(e)と (-f(-x))=x^5-(a)x^4+(b)x^3-(c)x^2+(d)x-(e) 
のガロア群は同じなのでeは正の整数のみ挙げています．従って[a,b,c,d,e]が可解ならば，[-a,b,-c,d,-e]も可解です．


(イ)
「4次の係数が0」で残りの係数の絶対値が15以下:
f(x)=x^5+(a)x^3+(b)x^2+(c)x+(d) (-15≦a,b,c≦15,1≦d≦15, a,b,c,dは整数)
のうち既約で可解な方程式を SageMath で数え上げました．これは 主に, アプリを使う方のためです．

F20,D5,C5の内訳は次のとおりです．

F20 61個, D5 109個, C5 3個　計173個．
