Question

Set a has 4 elements and set b has 7 elements. What can be the minimum and number of elements in a intersection b

Answer 1

Answer:

The answer is 0.

Intersection of two sets is the set of all those elements which are common in both the sets.

So if two sets A and B are disjoint sets means they do not have any common element then the number of elements in A intersection B will become 0.

Otherwise, it may be all the elements of a set that are common in both.

Maximum number of elements in A intersection B in your question is 4.
