8. Nathan has 3 jars, each containing either 5 or 10 marbles. Which of the following could NOT be the total number of
marbles in all the jars? 30, 20, 35, 25

35

Step-by-step explanation:

Because,

when we take the maximum values of marbles in a jar ,

that is each jar contains 10 marbles

then the total number of marbles in 3 jars is 30

so , the value 35 is not possible.

Thank you

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.
