Question

A={x:x is odd number and X is less than or equal to 10}
B={x:x=n2 +2,n£W and - 2 less than or equal to n, n is less than or equal to 3} then verify n(A union B) =n(A)+n(B) - n(intersection B) ​

Answer 1

Step-by-step explanation:

A={1,3,5,7,9}

B={-2,-1,0,1,2,3}

n (A union B)=9

n (A)=5

n(B)=6

n ( A intersection B)=2

9=5+6-2

9=11-2

9=9
