Rosa read 57 pagesof a book in the morning she read 13 fewer pegues in the afternoon how many pages dd rosa read in the afternoon

In the afternoon Rosa read 13 fewer pages as compared to the number of pages read in the morning

So we subtract 13 from 57 to get the number of pages read in the afternoon.

That is the number of pages read is the afternoon

Therefore Rosa read 44 papers in the afternoon

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.
