Suppose Set A contains 64 elements and the total number elements in either Set A or Set B is 79. If the Sets A and B have 1 elements in common, how many elements are contained in set B?

Respuesta :

Answer:

16

Explanation:

Set A contains = 64 elements

set A union B ( set A or set B) = 79

A intercept B = 1 which means

Set A contains 64 - 1 element that are not common with B = 63

then set B = 79 - 63 = 16
