I Put A.

anonymous · Answer

oh and now probability
really what kind of class is this?  random math class?

anonymous · Answer

criminal really
anyways, the symbol $\cap$ means "intersection" what is in both sets

anonymous · Answer

Its Algebra 2, Has everything x D i failed it my sophmore year, so im re-doing it

anonymous · Answer

i should say what is common to both sets
so no, not A
what numbers are divisible by two and also odd?

campbell_st · Answer

Well you are being asked what do A and B have in common... 

that is the intersection... 

so what do the sum is odd   and the sum is even have in common..?

usukidoll · Answer

so we need all numbers that are divisible by 2 in B... that's 2 4 6 8 10 ... yada yada

anonymous · Answer

i can see why
any one would fail such a random sample of questions 
no theme, nothing to hold it together

usukidoll · Answer

oh sorry read it wrong...

usukidoll · Answer

anonymous · Answer

?

usukidoll · Answer

~_~

anonymous · Answer

SOOO. It isnt A?

campbell_st · Answer

thats correct

anonymous · Answer

no dear
there is no number that is odd, and divisible by 2 (even)

usukidoll · Answer

sat is right... consider 27..  2 doesn't divide 27

anonymous · Answer

Think about what is in both sets of all odd numbers and divisible by 2

anonymous · Answer

Oh >.< Then WUT.

anonymous · Answer

confused yet?  choose the one that looks like $\{\}$ i.e. nothing

campbell_st · Answer

its a cube with numbers 1 to 6 on it... a different number on each face of the cube

campbell_st · Answer

you may call then dice(plural) or die(singular)

usukidoll · Answer

so the odd would be just 1 3 and 5 and the even 2 4 6

campbell_st · Answer

it's the sum of the faces on 2 dice is odd is A

the sum of the faces of 2 dice is even is B

usukidoll · Answer

like 2+3=5

campbell_st · Answer

usukidoll · Answer

what about 1 + 2 =3
