A8. 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):

x₁

x

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.
