If U=x:xisanaturalnumberlessthan20, then find its subsets P such that
P=evennaturalnumbers
P=2,4,6,8,10,12,14,16,18
Universal Set: A set that consists of all elements of different sets under consideration is called the universal set. It is represented by U or ξ
If U=x:xisanaturalnumberlessthan20, then find its subsets Q such that
Q=oddnaturalnumbers
If A represents the set of natural numbers less than 5, then find the number of elements in A.
Also, write the number of subsets.
If U= set of all whole numbers less than 12, A=set of all whole numbers less than 10, B= Set of all odd natural numbers less than 10, then what is (A ∩ B)'?
