Cars today have three-point seatbelts where one strap goes across the waist and another goes
across the body; these seatbelts are effective at the speeds at which cars travel. However,
fighter jets travel at much faster speeds, about 20 times faster than a commercial car nese
fighter jets accelerate so quickly that fighter pilots need to be strapped in more tightly. Do you
believe that these three-point seatbelts would be effective for pilots in a fighter jet? Evaluate
the problems the pilots might have with a three-point seatbelt by explaining the forces acting
on the pilot. Define the criteria and constraints for 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.
