A6. Suppose the joint probability function associated with data obtained in a study of automobile accidents in which a child (under age 5 years) was in the car and at least one fatality occurred is given in the table as follows: Table 1: Joint Probability function 1 Y₁/YO Total 0 0.38 0.17 0.55 1 0.14 0.02 0.16 2 0.24 0.05 0.29 Total 0.76 0.24 1.00 where Y₁ is the number of seat belts in use at the time of the accident and Y₂ is the number of fatalities per child. Calculate the covariance and correlation between Y₁ and Y₂.
