It takes 15 minutes for the interior temperature of an oven to rise from 20°C to 180°C. A cake is placed in the oven for 25 minutes. When the cake is removed, the oven is turned off. The interior temperature of the oven returns to 20°C after 15 minutes. The oven is then turned on again, 45 minutes later. It takes 10 minutes for the temperature to reach 165°C. Cookies are placed in the oven to bake for 20 minutes. When the cookies are removed, the oven is turned off. The interior temperature of the oven returns to 20°C after 10 minutes. How can I make a line graph with this?

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.

the answer is a.
