Which list of numbers is shown on the number line below? a number line going from negative 3 to positive 2. there are 4 equal spaces between each number. a point is halfway between negative 3 and negative 2. a point is between the second and third mark between negative 2 and negative 1. a point is on the mark 1 space to the right of 0. a point is halfway between 1 and 2. negative 2.5, 1 and three-fourths, 50 percent, 1.5 negative 2.5, negative 1 and one-third, 50 percent, 1.5 negative 2.5, negative 1 and three-fourths, 25 percent, 1.5 negative 2.5, negative 1 and one-third, 25 percent, 1.5

Step-by-step explanation:

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.
