It takes 232323 minutes for 666 people to paint 666 walls. how many minutes does it take 999 people to paint 999 walls?

232323 minutes

Step-by-step explanation:

From the question, 666 are painting 666 walls. This means that 1 wall is painted by 1 person. If each person completes their painting in 232323 minutes, it means that all the walls will be painted in 232323 minutes.

When the number of people are increased to 999 with the walls increased to 999 also, we assume 1 person will paint 1 wall each again. This means that each person paints the wall in 232323 minutes as well.

Therefore, it will take 232323 minutes for 999 people to paint 999 walls.

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.
