Answer 1

Answer:

please mark me as brainliest

Step-by-step explanation:

Q1

If A=(6,7,8,9),B=(4,6,8,10) and C={x:xϵN:2<x≤7} ; find : A−(B∪C)

Q2

If A = (6, 7, 8, 9), B = (4, 6, 8, 10) and C = {x : xϵN : 2<x≤7} ; find :

A - B

Q3

Let U = { x∈N:1≤x≤10 } be the universal set, N being the set of natural numbers. If A={1,2,3,4} and B={2,3,6,10} then what is the complement of (A−B) ?
