Javier and 2 of his friends, James and Alex, are planning on taking a trip to Miami, FL. They plan on driving and would like to rent a car. They have a choice of two rental cars, each coming with a full tank of gas. The compact car has a 16 gallon tank and averages 25 miles per gallon. The midsize car has a 21 gallon tank and averages 20 miles per gallon.

29 is the correct answer

step-by-step explanation:

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.
