Answer 1

In the above question,

	3	5	7
$P(X~=~x)$	$\frac{1}{2}$	$\frac{5}{8}$	14

this is not a discrete probability distribution,

Hence, the decision is NO.

The reason behind this decision is that the sum of the probabilities is not equaled to 1.

i.e. for becoming a probability distribution, the sum of the total probabilities must be equal to 1.

Here, we can sum all the given probabilities:

2 +-= 0.5 + 0.625 + 0.25 1.375

that is why it is not a probability distribution.
