Because the order doesn't matter on where each person sits use the combinations formula:
C = n! / (r!(n-r)!)
Where n is the total number of people and r is the number of chairs.
C = 6! / (4!(6-4)!)
C = (6*5*4*3*2*1) / ((4*3*2*1(2*1))
C = 720 / (24*2)
C = 720 / 48
C = 15
There are 15 different arrangements.
Answer:
5/8+3/4-2/3-5/6
= ( 5/8 + 3/4 ) - ( 2/3 + 3/4)
= ( 11/8) - (17 /12)
= 11/8 - 17/12
= 33-34 /24
= -1/24 (ans)
