we have an uneven die with 8 faces with numbers 1 through 8. the probability of each number coming up is proportional to the number itself. for example the probability of 2 coming up is twice the probability of 1 coming up, and so on. find PMF of x
Accepted Solution
A:
Answer:Step-by-step explanation:Given that uneven die with 8 faces with numbers 1 through 8the probability of each number coming up is proportional to the number itself.P(x)= kx, x =1,2,3...8To find k:Since total probability =1we have \Sigma_1^10 kx =1Simplify to get36k =1: k = 1/36Hence distribution of X is as follows:x 1 2 3 4 5 6 7 8 Total
p(x) 1/36 1/18 1/12 1/9 5/36 1/6 7/36 2/9 1
