Answer:
D. No comma because the total probability is not equal to 1.
Step-by-step explanation:
Given the distribution:
[tex]\left|\begin{array}{c|cccccc}x&0&1&2&3&4&5\\ P(x)&1/25&1/5&1/2&3/4& 1/50&1/100\end{array}\right|[/tex]
The sum of the probabilities
[tex]\sum P(x)=1/25+1/5+1/2+3/4+ 1/50+1/100\\\sum P(x) =1.52 \neq 1[/tex]
Therefore, the distribution is not a probability distribution because the total probability is not equal to 1.
The correct option is D.
