Select the statements that are true based on the following given information.

D = {x | x is a whole number}

E = {x | x is a perfect square < 36}

F = {x | x is an even number between 20 and 30}

The expression D ∩ E is {1, 4, 9, 16}.
The expression D ∩ F is {12, 14, 16, 18}.
D ∪ (E ∩ F) is {all whole numbers}.
(E ∩ F) is the empty set.
The expression D ∩ (E U F) is 25

good luck!

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

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.
