Answer:
Given : (q: 8,4,2,1)
q = 15
List all coalitions ( 2 pair)

Those whose total weight is equal to q or more than q will go further in the list of winning coalitions
Since No pair's total weight is equal to q or more than q . So, we will not consider then further
Coalitions ( 3 pair or more)

Those whose total weight is equal to q or more than q will go further in the list of winning coalitions
winning coalitions:

If Player 1 leaves
So, total weight will be 4+2+1 = 7
So, Player 1 is critical
If Player 2 leaves
So, total weight will be 8+2+1 = 11
So, Player 2 is critical
If Player 3 leaves
So, total weight will be 8+4+1 = 13
So, Player 3 is critical
If Player 4 leaves
So, total weight will be 8+4+2 = 14
So, Player 4 is critical

Answer:
a. -29
b. 7
c. 7.04
d. 1/6
Step-by-step explanation:
Here, we want to calculate the difference between the numbers;
a. -8 and 21
That would be -8-21 = -29
b.-87 abs -94
= -87-(-94)
-87 + 94= 7
c. 1.8 and -5.24
= 1.8 -(-5.24)
= 1.8 + 5.24 = 7.04
d. 1/3 and 1/6
= (2-1)/6 = 1/6
