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:
B = {x : x ∈ W ; x is less than 100}.
The set, given below, state whether it is finite set, infinite set or the null set:
{even numbers not divisible by 2}
Fill in the blank:
Every set is a _____ of itself.
Fill in the blank:
If A is a proper subset of B, then n (A) _____ n (B).
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)
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)
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(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).
Let n(A) 30, n(B) = 27 and n(A∪B) = 45, find: n(A - B).
