1,2,3
Step-by-step explanation:
1x2x3=6
1+2+3=6 best answer
The 3rd one because you have to get the y-intercept also which is -6
18 choose 7
=C(18,7)
=18!/(7!(18-7)!)
=31824
OR
18 choices for first passenger,
17 choices for second passenger,
....
12 choices for 7th passenger,
so total = 18*17*16...12
but there are 7! ways to order the 7 passengers, so
number of groups
=18*17*16...12/7!
=31824 as well
