Just thought I'd spread some positivity for anyone who needs it:) U got this. if u find urself struggling, feeling like u have no purpose or dont feel like ur improving, it takes time and a process. you have to trust ur self and the process, but i promise ur capable of soo much and u will overcome whatever ur going through. your beautiful, special, important, and loved.

Step-by-step explanation:

Needed that =)

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.
