Write the sum using summation notation, assuming the suggested pattern continues. 100 + 121 + 144 + 169 + + n2 + (2 points) summation of n squared from n equals eleven to infinity summation of n minus one squared from n equals ten to infinity summation of n squared from n equals ten to infinity summation of n plus one squared from n equals ten to infinity

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.
