How many different ways can seven students be seated in a row of seven seats if there must be exactly two people between Alex and Betsy?
Thank you so much!
There are 6*2!*5!*3 = 4320 possible seatings.
Hm...I don't believe that works. The answer choices are 820, 960, 1210, 1480, and 1528. Thank you a lot for trying, though--
