Write the cardinal number of the following set:
B = Set of numbers on a clock-face.
The set, given below, state whether it is finite set, infinite set or the null set:
{natural numbers more than 100}
The set, given below, state whether it is finite set, infinite set or the null set:
A = {x : x is an integer between 1 and 2}
The set, given below, state whether it is finite set, infinite set or the null set:
{multiples of 8}.
M = {x : x is a natural number between 0 and 8) and N = {x : x is a natural number from 5 to 10}. Find: M – N and n(M – N)
M = {x : x is a natural number between 0 and 8) and N = {x : x is a natural number from 5 to 10}. Find: N – M and n (N – M)
If A = {x: x is natural number divisible by 2 and x< 16} and
B = {x:x is a whole number divisible by 3 and x < 18}, find: A ∩ B and n (A ∩ B).
If A = {x: x is natural number divisible by 2 and x< 16} and
B = {x:x is a whole number divisible by 3 and x < 18}, find: n(A – B)
Let A and B be two sets such that n(A) = 75, M(B) = 65 and n(A ∩ B) = 45, find: n(A∪ B)
Let A and B be two sets such that n(A) = 45, n(B) = 38 and n(A ∪B) = 70, find: n(A - B).
