Question

set F has 10 elements,set G has 15 elements,and F intersection F has 15 elements .how many elements are in F Union G?explain​

Answer 1

your question is wrong pls check

Answer 2

Number of element in F∪G is 10

Step-by-step explanation:

• Given data

        Number of element in set F

        N(F) = 10

        Number of element in set G

        N(G) = 15

        Number of element in F intersection G

        N(F∩G) =15

• Here is common element are in set F and set G.

• We know relation between intersection and union, which are given below

• N(F∪G) =N(F) + N(G) - N(F∩G)

        N(F∪G) = 10 + 15 -15

        So

        N(F∪G) = 10 = This is number of element in F Union G
