Question 4 An unfair die looks like an ordinary six-sided die but the outcomes are not equally likely. The probability distribution of the face value, X, is as follows: 2 3 0.2 0.31 1 -21) (0.15 Ti P(X = xi) P(X=1) X=5 |P(X=4)=0.19 4 P(X=1) 0.19 5 0.12 1. Use the random variable notation to express symbolically each of the following: The probability that the face value is exactly 4 is equal to 0.19. 6 The probability that the face value is exactly 1. 0.03 Total 1
