Ashley one 129 pieces of gum playing our county fair at school she gave every student in her math class four pieces she has nine remaining how many students are in her class

The answer is 30.

Step-by-step explanation: I subtracted 9 from 129 and got 120. I then divided it by 4 and I got 30. Hope this helped.

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.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
