A fair tetrahedral die has four triangular faces, numbered 1, 2, 3 and 4. The score when this die is
thrown is the number on the face that the die lands on. This die is thrown three times. The random
variable X is the sum of the three scores.
(i) Show that P(X = 9) = 10
64.
Can anyone pls solve this part with an explanation for each step?

Consider the linear model for a two-stage nested design with b nested in a as given below. yijk=\small \mu + \small \taui + \small \betaj(i) + \small \varepsilon(ij)k , for i=1,; j= ; k=1, assumption: \small \varepsilon(ij)k ~ iid n (0, \small \sigma2) ; \small \taui ~ iid n(0, \small \sigmat2 ); \tiny \sum_{j=1}^{b} \small \betaj(i) =0; \small \varepsilon(ij)k and \small \taui are independent. using only the given information, derive the least square estimator of \small \betaj(i) using the appropriate constraints (sum to zero constraints) and derive e(msb(a) ).
