Solution:

we considet the 2 sources are independent

P(rain)=P(Abousoun is right&sweets_Hsn is wrong)=3/4x1/3=1/4
P(no rain)=P(Abousoun is wrong&Sweets_hsn is wright)=1/4x2/3=1/6

halla2 probabilite la boukra tchatte:

(Nb de cas favorables)/(nb de cas possibles)=P(rain)/[P(rain)+P(no rain)]=0.6

mish ossit mamnou3 el fractions .. you can use the division or fraction
but in the final answer ... all have nombre entiers

example the dad had 1001 $
gave maid 1 $
oldest son : (1001-1)/5 = 200 $
and so on ....
ya3ne ma fi 200.42 $ or 200$ and 42 Cents
