4 * 3 * 2 = 24
24 ?
24 is correct, Jimmy Barcus.
Think of naming the people A, B, C and D. If A sat on the left then the others could sit in one of these ways: BCD, BDC, CBD, CDB, DBC, DCB – 6 ways. But any one of the four could sit on the left seat, so we must multiple our answer by 4, giving 24.
Great job, you’re today’s winner.
4! with ! being the mathematical symbol
but once someone sits in it the seat is no longer empty.
