Suppose X₁ is a random variable which takes values (x₁,x) and X₂ is a random variable which takes values (x,x). Below is the table with values for joint probability P(X1, X2): x2 0.3 0.1 x2 0.4 0.2 which of the following statements is correct? A: P(X₁ = x₁, X₂ = x₂) = 0.3, B: P(X₁ = x₁) = 0.4, C: P(X₂ = x₂) = 0.2. Consider a coin experiment, where out of 10 trials, 3 successes were observed. Suppose that the Beta-Binomial model (with a uniform prior) was selected to fit the data. Which of the below is TRUE? Hint: Recall that the Probability Mass Function (PMF) for the Binomial distribution is P(x = k) n! (n- -k)!k!! Beta distribution is F-1 (1-0)³–¹1) T(a+B) T(a)r (3) = 0k (1 – 0)n—k, and the Probability Density Function (PDF) for the A: posterior p(x) ∞ Beta(4,8) B: posterior p(x) x Beta(12,5)
