Suppose X₁ is a random variable which takes values (x₁,x) and X₂ is a randomvariable which takes values (x,x). Below is the table with values for joint probabilityP(X1, X2):x2 0.3 0.1x20.4 0.2which 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. Supposethat the Beta-Binomial model (with a uniform prior) was selected to fit the data. Whichof the below is TRUE?Hint: Recall that the Probability Mass Function (PMF) for the Binomial distributionis 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 theA: posterior p(x) ∞ Beta(4,8)B: posterior p(x) x Beta(12,5)
