Mammograms are used to detect breast cancer. Suppose a mammogram is known to be 83% accurate, which means
P(positive mammogram/cancer) = 0.83. Suppose in the United States, 37 million women are tested for breast cancer with
mammograms and, of these, 190,000 have breast cancer (regardless of the results of the mammogram). Complete parts (a)
through (c) below.
