Answer #1

a. The required probability

1-(0.412+0.325+0.107+0.039+0.033+0.025)=1-0.941=0.059

b) probability that the patient’s principal source of payment is Medicare, Medicaid, or some other government program:0.325+0.107+0.059=0.491

The payment mode can be any one of the 3,that is events are mutually exclusive of one other, so P(Medicare or Medicaid or Other Govt. Program) =P(Medicare) +P(Medicaid) +P(Other Govt Program)

c) Given that the principal source of payment is NOT a government program, the probability that it is Private Insurance=P(Private Insurance|NOT Govt Program=P(Private insurance and NOT Govt program) /P(Not Govt Program)

=P(Private insurance) /P(NOT Govt Programe) =0.412/0.941=0.4378

A private insurance mode of payment and a not Govt program can together happen iff it is only a private insurance payment
