Question

# Two sets A and B are disjoint if and only if

Hint:

### The totality of the natural numbers is gathered in the set N. Following is a representation of Set N:For example: N = { 1, 2, 3, 4, 5…}Sets without any elements are referred to as empty sets, void sets, or null sets, and they are symbolised by the symbols or.Singleton Set: A set that only contains one element is referred to as a singleton set.Sets can be either finite or infinite. A finite set has a finite number of elements, whereas an infinite set has an infinite number of elements.Equal Sets: Two sets A and 6 are deemed to be equal if each element in A is also an element in B, or vice versa, i.e., two equal sets will include the exact same element.Two finite sets A and 6 are said to be equivalent if their element counts are equal.Now consider an example:Set A = {1, 2, 3)Set B = {4, 5, 6}Then A-B = { }Which means

So here we used the concept of sets and understood the notations that are used. We also understood the different types of sets that are present. Two sets A and B are disjoint if and only if .
