Question:

For three events, A,B,C, consider the following probabilities: A,B,C have probability 20% of occurring, the probability of any two of these events occurring is 3% for each pair, and the probability of all three occurring is 1%. Using DeMorgan's first law, find the probability of (A C)c.
