Let u represent the set of people in a certain community who were asked if they subscribe to an information source. let d ={ x ∈ u | x subscribes to the daily informer } and n ={ x ∈ u | x subscribes to news magazine } (assume these sets are not disjoint.) write the set that represents the set of people surveyed who subscribe to exactly one of the two news sources given.

a. n ∪ d
b. ( n c ∩ d ) ∪ ( n ∩ d c )
c. n c ∩ d
d. ( n ∩ d )c
e. ( n c ∪ d ) ∩ ( n ∪ d c )

b.

Step-by-step explanation:

Here,

N = { x ∈ U | x subscribes to News Magazine },

D = { x ∈ U | x subscribes to The Daily Informer },

Such that N∩D ≠ ∅,

Now, the number of the set of people surveyed who subscribe only News Magazine

= Subscribe News Magazine and not Daily Informer

=

Similarly, the number of the set of people surveyed who subscribe only Daily informer

= Subscribe Daily informer and not subscribe News Magazine

=

Hence,  the set of people surveyed who subscribe to exactly one of the two news sources given

= Subscribe News Magazine and not subscribe Daily Informer or subscribe Daily informer and not subscribe News Magazine

da freeck kinda math is this just drop out
