A company manufactures a popular style of chair. The price-demand function for this chair is given by
p(x)=250−x,
where x is the number of chairs sold. The fixed cost of production for this chair is $125 and the variable cost is $50. What is the company’s profit if they manufacture 50 chairs? Do not include a dollar sign or commas in your answer.

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.

your answer is option c.
