6. braden scored 9 fewer poinis on his moth test
than ava did. if ava scored an 86. what was
braden’s score?

77 points :)

Step-by-step explanation:

If Ava scored 86 points, and Braden scored 9 fewer points than her, we need to subtract to find out how many points Braden scored:

86 - 9 = 77

b) well because you get well

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.
