5. no, because each number isn't given the same amount of space. this means other numbers have a higher probability of being spun than others.

6. yes, because a cube has 6 sides so each number will have an equal probability of being rolled.

7. 12%

8. he's less likely to pull a blue one from the bag of 250 because there's a smaller percentage of blue in the bag of 250 than the bag of 25.

Step-by-step explanation:

7. 3/25 = 0.12 = 12%

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.
