Plz me now i need all questions answered simplify the expression. 2x + 5 + 3x + 1 simplify the expression. -3x + 6 + -4x + 2 simplify the expression. -2x + -5 + 8x + -4 simplify the expression. -3x - 6 - 4x + 8 simplify the expression. 6x - 3 -9x - 2 distribute. 4(x + 3) distribute. 3(x - 2) = distribute. -2(x + 4) distribute. -3(-2x - 1) distribute. 4(3x + 5)

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.
