Solution
It seems like there's a formatting issue with your question, making it difficult to understand. However, I can tell you that if X is a random variable with a given distribution, the sum of all probabilities in that distribution should equal 1.
If we denote the probabilities as follows:
P(X=0) = 0 P(X=1) = k P(X=2) = 2k P(X=3) = 2k P(X=4) = 3k P(X=5) = 2k P(X=6) = 2k P(X=7) = k
Then, the sum of these probabilities should be 1, i.e.,
0 + k + 2k + 2k + 3k + 2k + 2k + k = 1 12k = 1 k = 1/12
Please check your question and provide the correct distribution if this is not what you were asking.
