Apublisher for a promising new novel figures fixed costs (overhead, advances, promotion, copy editing, typesetting, and so on) at $63,000 and variable costs (printing, paper, binding, shipping) at $2.30 for each book produced. if the book is sold to distributors for $13 each, how many must be produced and sold for the publisher to break even?

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.
