A paper book is shaped like a rectangular prism. The cover of the book measures 5 inches by 8 inches, and the book is 2 inches thick. Calculate the volume of this book

80 in³

Step-by-step explanation:

Since it is a rectangular prism, all you have to do is multiply all the side lengths together to find the volume.

(2)(5)(8) = 80 in³

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.
