The fish population in a certain lake rises and falls according to the formula F = 4000(25 + 17t- t^2).
Here F is the number of fish at time t, where t is measured in years since January 1, 2003, when the fish population was first estimated.
(a) on what date will the fish population again be the same as it was on January 1, 2003?
June 1
(b) By what date will all the fish in the lake have died?

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.
