Question

5. Are the sets A={1,2,3,4), B = {x:xeN and 5 <x<7} disjoint? Why?
​

Answer 1

Answer:

yes,

Step-by-step explanation:

because,

A = {1,2,3,4}

and

B = {6}

so,

(A U B) = { 1,2,3,4,6}

here is not continuous counting, so it is disjoint ,

I hope it will helps you,

Answer 2

Answer:

YES

EXPLANATION:

A = {1,2,3,4}

B = {6} (GREATER THAN 5 AND LESS THAN 7)

THAT'S WHY THERE IS NO COMMON CHARACTER IN BOTH OF THEM SO, IT'S A DISJOINT
