Answer:
Step-by-step explanation:
Answer:
3 two-person committee's can be formed from a group of six people
Y = 2/x
x must not have the value of 0 because x is used as a denominator.
A denominator must not have a value of 0 because the overall value of the fraction is undefined.
x may be any positive or negative integer.
x = 1
y = 2/1 = 2 ⇒ (1,2)
x = 2
y = 2/2 = 1 ⇒ (2,1)
x = 3
y = 2/3 = 0.67 ⇒ (3, 2/3)
x = -1
y = 2/-1 = -2 ⇒ (-1,-2)
x = -2
y = 2/-2 = -1 ⇒ (-2, -1)
x = -3
y = 2/-3 or -0.67 ⇒ (-3, -2/3)
It should be 4/7 ! If I'm wrong I apologize- but I hope this helps :)
