The diagram represents two statements: p and q.

which represents regions a, b, and c?

p ∨ q
p → q
q ∧ p
q → p

A.

Step-by-step explanation:

We are given that

A region: It includes all element of p but not q.

B region: It includes elements of p and q.It is represented by

.

C region: it contained the elements of q only.

Union of A , B and C are represented by

Hence, the region A,B and C represents by

Option A is true.

step-by-step explanation:

i think you should think about the question and not look online.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
