M = {x/x is an integer , and -3<x<6} , N = the set of positive integers that are less than 8.
Find M∩N. (3 marks)
- A = {x/x is a positive integer that is divisible by 3}, B = {x/x is a positive integer that is
divisible by 5. Find (a) A∩B (b) L.C.M of 3 and 5
- J = {1,2,3,4,……} the set of positive integers and P = {x/x is a prime number} ,find J∩P.
4.A = {x/x is a positive even integer }. B = { x/x is a prime number}. C = { x/x is a positive
integer that is divisible by 3}. Find (a) A∩ (B∩C) and (A∩B) ∩C.
Show that A∩ (B∩C)= (A ∩ B) ∩ C
