How much paper did it take to cover the gift

150 cm

Step-by-step explanation:

If the paper did not overlap, that means we have to take out the total surface area of the cube. Total surface area is basically all the sides we can touch; which in this case are 6. So area of one side is 5x5= 25

And we multiply that by 6

Hence, 6x25= 150

Step-by-step explanation:

If wrong height * length

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.
