To determine the number of deer in a game preserve, a forest ranger catches 630 deer, tags them, and releases them. Later 179 deer are caught, and it is found that 42 of them are tagged. Assuming that the proportion of tagged deer in the second sample was the same as the proportion of tagged deer in the total population, estimate the number of deer in the game preserve. The number of deer in the game preserve is:.

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.
