shusha [124]

The expected value of health care without insurance is $437.25.

The expected value of health care with insurance is $1,636.40.

<h3>What are the expected values?</h3>

The expected values can be determined by multiplying the respective probabilities by its associated costs.

The expected value of health care without insurance

                                                         = (1 x 0) + (0.32 x 1050) + (0.45 x $225)  

                                                         = $437.25

The expected value of health care with insurance

                                                          = (1 x 1580) + (0.32 x 75) + (0.45 x $72)

                                                          = $1,636.40

Thus, The expected value of health care without insurance is $437.25.

         The expected value of health care with insurance is $1,636.40.
