Recent news articles have discussed the connection between a rare genetic mutation and breast cancer in women. One of the companies offering this BRCA genetic test is Quest, and this company claims a 98% accuracy rate. In the general population about 1 in 420 people would actually carry this BRCA1 genetic mutation. Hint: Construct a table as in your course materials. Use a population size of 42000 women.

What is the likelihood that someone does not have the BRCA mutations, if they test positive?
