A fair triangular spinner has sides labelled 0,1 and 2, and another fair triangular spinner has sides labelled –1, 0 and 1. The score, X, is equal to the sum of the squares of the two numbers on which the spinners come to rest.

a. List the five possible values of X.

b. Draw up the probability distribution table for X.

c. Given that X < 4, find the probability that a score of 1 is obtained with at least one of the spinners.

d Find the exact value of a, such that the standard deviation of X is 1/a × E(X).
