# Conditional Probability

2) The Positively Charged company uses capacitors from two different manufacturers. Historically, 60% of the capacitors come from manufacturer 1. While 90% of capacitors from manufacturer one pass quality-control checks, only 75% of the capacitors from manufacturer two pass the checks. A capacitor selected at random is found to be faulty. What is the probability it was from manufacturer 2?
