NO EXPLANATION IS NEEDED! WILL MARK BRAINLIEST IF YOU GET IT RIGHT! 7TH GRADE MATH PEOPLE, DO NOT ANSWER THIS WRONG PLEASE!!! (sorry for the caps, wanted to catch attention)

Anyways so the problem that I am having trouble with is in the file that is attached to this question. Please answer it correctly.
I need these answers by midnight EDT and well I am really in a pickle right now since I can not find the answers. I also am having trouble with two other questions so if you want the extra points go on my profile and check out my last question where I had two of these for quite a bit of points.
ANSWER ALL PARTS OF THIS QUESTION, if you do not the whole thing gets marked wrong.

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.

the answer is option a you would get more money.it would be $250.

step-by-step explanation:

for option b 200/2=100=50% 100/2=50=25% 50/5=10=5% it would be $220

the answer to this is:

factor 2x2+16x+24

2x2+16x+24

=2(x+2)(x+6)

answer:

2(x+2)(x+6)

hope this hmu if needed
