  1. a. 10% out of 100% failed A or 10/100
    3% of 100% failed A & B or 3/100
    3% that failed A(10%) also failed B or 3/10

    b. 12% out of 100% failed B
    3% out of 100% failed A & B or 3/12

    c. failed A - 10%
    failed B - 12%
    sub total 22%(-3% counted double-failed both)
    = 19% total

    d. 100%-19% that failed =81% chance product did not fail.
