Question

11. A = [1,2,3,4,5,6), B = (4,5) find n(A - B).​

Answer 1

Step-by-step explanation:

1 a_ 123456

2 b_45 ok then find na-b

Answer 2

Answer:

n{A-B} = {1,2,3,6}

Step-by-step explanation:

Given in the question

Set A = {1,2,3,4,5,6}

Set B = {4,5}

We need to calculate

n(A-B) = ?

this can be calculated as

n(A-B) = {1,2,3,4,5,6} - {4,5} = {1,2,3,6}
