Question

help me guys please. ​

Answer 1

Step-by-step explanation:

Given :-

A = { a,b,c,d }

B = {b,d,c,f}

To find :-

Find the following :

1) AUB

2)AnB

3) n(A)

4) n(B)

5) n(AUB)

6) n(AnB)

Solution :-

Given sets are A = { a,b,c,d }

=> Number of elements in A = 4

=> n(A) = 4

B = {b,d,c,f}

=> Number be f elements in B = 4

=> n(B) = 4

AUB

=> {a,b,c,d} U { b,d,c,f}

=> {a,b,c,d,f}

AUB = {a,b,c,d,f}

=> Number of elements in AUB = 5

=> n(AUB) = 5

and

AnB = {a,b,c,d} n { b,d,c,f}

=> AnB = { b,c,d}

=> Number of elements in AnB = 2

=> n(AnB) = 2

Answer :-

1) AUB = {a,b,c,d,f}

2)AnB = { b,c,d}

3) n(A) = 4

4) n(B) = 4

5) n(AUB) = 5

6) n(AnB) = 3
