zarkam21:
okay
Vocaloid:
area 2 + area 1 = girls = 30
zarkam21:
okay
Vocaloid:
area 1 + area 3 = seniors = 24
zarkam21:
so area 1=6
area 2=30
area 3=24

Vocaloid:
think carefully
Vocaloid:
area 1 = 6
area 2 + area 1 = 30
area 3 + area 1 = 24
solve for area 2 and area 3
zarkam21:
24
18
zarkam21:
24
18
Vocaloid:

anyway, for junior boys we would just subtract 70 - area 1 - area 2 - area 3
zarkam21:
2
zarkam21:
2
Vocaloid:
I get 22
zarkam21:
70-6=64
64-24=20
20-18=2

I apologize
Vocaloid:
nah it's no problem ^^
anyway, write those four numbers where it says areas 1,2,3,4
Vocaloid:
anyways, for part II, we need to find senior girls/total seniors
Vocaloid:
so it would just be 6/24 (using the information from the paragraph)
Vocaloid:
or 1/4

zarkam21:
wait for the four number infilling in the veen diagram it would be 6,24,18
Vocaloid:
yes, 6, 24, 18, then 22 for areas 1,2,3 and 4 in that order
zarkam21:
and then 6/24=1/4 for the second part
Vocaloid:
yes
zarkam21:
okay so for part 3

Vocaloid:
for III we need to find junior girls/total girls
Vocaloid:
so area 2/(area 2+1) = ?
zarkam21:
24/(24+6)
24/30
Vocaloid:
good (so 4/5)
