What is the solution of the equation?
-1 =V
-
3

I think you mean "-1=v-3" which if that is the case the answer is V=4

Step-by-step explanation:

To know what is V you got to make remove the -3 and transfer it to the other side, which will change its' sign so it will be +3

the new equation: +3-1 = V

the 2 = v

Meaning that V is 2,

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.
