Question about what field this problem would belong to

  1. Apr 9, 2013 #1
    An insurance company pays hospital claims. The number of claims that include emergency room or operating room charges is 85% of the total number of claims. The number of claims that do not include emergency room charges is 25% of the total number of claims. The occurrence of emergency room charges is independent of the occurrence of operating room charges on hospital claims.

    Calculate the probability that a claim submitted to the insurance company includes operating room charges.


    What would I need to study to solve this problem? Are there any resources that I can get for free online?

    This is a basic probability question. The videos here should help you with that.
