Need help with math its a struggle

First 3 yes, last 3 no

Step-by-step explanation:

This is solved by following the (x,y) cords.

So for the first three, they are in the section of purple or the section where the 2 inequalities overlap (which means it is a solution to both)

The same can be followed for the last two however the 4th one is a little funky. The reason why that is false is because the line is dotted meaning that the numbers on the line are not solutions to the second lower inequality so it is not a solution to the problem.

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.
