    Answer:

    0.717 or 71.7%

    Step-by-step explanation:

    P(M) = 0.852

    P(D) = 0.759

    P(M or D) = 0.894

    The probability that a randomly selected American has both medical and dental insurance is given by the probability of having medical insurance, added to the probability of having dental insurance, minus the probability of having either insurance:

    P(M\ and\ D) = P(M)+P(D)-P(M\ or\ D)\\P(M\ and\ D) =0.852+0.759-0.894\\P(M\ and\ D) =0.717=71.7\%

    The probability is 0.717 or 71.7%.
