Answer:
Table 1 is the only table which represents PROBABILITY DISTRIBUTION table.
Step-by-step explanation:
In any given probability distribution:
1) The probability of each event should be strictly POSITIVE. 
2) Sum of all events in a a distribution should be 1.
Now, here 
A) All of the values of probability (0.11, 0..5, 0.49,0.35)  are positive.
Also, 0.11 +  0.5 +  0.49 + 0.35  = 1
So, the given table is a PROBABILITY DISTRIBUTION.
B)The table is NOT a PROBABILITY DISTRIBUTION as here
P(Blue) =  -1, which is negative.
C)The table is NOT a PROBABILITY DISTRIBUTION as here
P(Green) =  -0.49, which is negative.
D)The table is NOT a PROBABILITY DISTRIBUTION as here
P(Purple) =  -0.1, which is negative.
Hence, table 1 is the only table which represents  PROBABILITY DISTRIBUTION table.
