A. o = __
B. the table is not a probability distribution.

The table for this problem

Explanation / Answer

It is not a probability distribution since the second condition from the following two conditions is not met.

1. The probability of each value is between 0 and 1.

2. The sum of the probabilities =1

The sum of the probabilities =0.002+0.028+0.107+0.263+0.453=0.853

Which is not equal to 1
