Someone damaged the flag
Assume you have a USA flag. Also assume that it is magical. Why? Because this is a maths problem.
So the USA flag has 50 stars, positioned in 9 rows, the odd-numbered rows have 6 stars each, while the other have 5 stars each.
And so someone (maybe your pesky little brother) knocked the stars off the flag. He also made all the stars distinct by writing a number 1 to 50 on each star.
How many ways can you put back the stars into 9 rows, the odd-numbered rows have 6 stars each, while the other have 5 stars each?
Round to 3 significant figures
Note: Stars are distinct Rows are distinct Position on rows are not distinct (i.e. first in first row is no different from second in first row)
