(a) 
0.10.010.050.030.010.20.6
Here each of the numbers p() is positive and less than
Sum of probabilities

= 1$$
Thus the assignment is valid
(b)
Here each of the number p() is positive and less than
Sum of probabilities


Thus the assignment is valid
(c) 
0.10.20.30.40.50.60.7
Here each of the numbers p() is positive and less than
Sum of probabilities
=



 

Thus the assignment is not valid
(d)
-0.10.20.30.4-0.20.10.3
Here p and p are negative 
Hence the assignment is not valid
(e)

Hence the assignment is not valid
