PLEASE HELP ME AND MY DAD ARE STUMPED The following is an incorrect flowchart proving that point L, lying on line LM which is a perpendicular bisector of segment JK, is equidistant from points J and K:

What is the error in this flowchart?

1) JL and KL are equal in length, according to the definition of a midpoint.
2)An arrow is missing between ∠LNK = 90° and ∠LNJ = 90° and ∠LNK ≅ ∠LNJ.
3)An arrow is missing between the given statement and ∠LNK ≅ ∠LNJ.
4)Triangles JNL and KNL are congruent by the Angle-Angle Side (AAS) Postulate.

Point L is equidistant from endpoints J and K, not J and N.

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.
