Step-by-step explanation:
1 worker = 30 hours a week
1 worker = 30 x $5.50 a week = $165
1 worker = $165
1000 workers = 165 x 1000 = $165 000
If all 25 questions are different,
When order of selection counts:
P(25,7)
=25!/(25-7)!
=15511210043330985984000000/6402373705728000
=2422728000
When order of selection does not count count:
C(25,7)
=25!/(7!*(25-7)!)
=15511210043330985984000000/(6402373705728000*5040)
=480700
