Firstly tell me what are the number divisible by 2 between 1 to 10??

dmezzullo · Answer

2,4,6,8,10

anonymous · Answer

Yep so D = {2, 4, 6, 8, 10} and C = {2, 3, 4, 5}

So C union D will be all the digits together with no repetition..

anonymous · Answer

Sorry we are to find Intersection, so C Intersection D will be the common digits in C and D..

anonymous · Answer

So, what are the common digits in C and D???

dmezzullo · Answer

2, 3, 4, 5, 6, 8, 10}

anonymous · Answer

Common in both dear..

anonymous · Answer

The digits which are common in both C and D..

anonymous · Answer

anonymous · Answer

Okay, take your time..

dmezzullo · Answer

Oh 2 and 4

anonymous · Answer

Yep.. :)

So, Intersection means Common things that must be present in both the sets...

Got it??

anonymous · Answer

So, make a set of 2, 4 means:
