The probability that the majority of a three person jury will convict a guilty person is given by the formula P (x, y, z) = xy(1 − z) + (1 − x)yz + (1 − y)xz + xyz subject to constraint x + y + z = α, where x, y, z represents each jury members’ probability of reaching a guilty verdict and α is some constant that is generally less than or equal to the number of jurors. Find the values of x, y and z that maximizes the probability of convicting a guilty person when α = 0.75
