Question 5 A subject looks at an image consisting of two simple objects, O₁ and O2, while an eye-tracker returns the (x, y) coordinates of the focus of his gaze. When the subject looks at O₁, the a coordinate of the focus of gaze is characterised by a Gaussian probability density function 9₁ with mean -5 and variance 5, while a Gaussian probability density functiom 92 with mean 5 and variance 7 is used for object O₂. The probabilities that the subject looks at objects O₁ and O₂ are P(O₁) = 0.6 and P(O2₂) = 0.4. 1. Calculate the posterior probability P(0₁|x = 1) 2. Is it more probable that the subject was looking at object O₁ or O₂?
