Step-by-step explanation:
For this problem, it is asking for the probability of one event or the other so the probabilities of each event happening should be added together, and then the probability of both happening must be subtracted from that total.
In this case you would take P(woman) + P(2 door) - P(woman and 2 door).
This gets (270/600) + (280/600) - (150/600) = 400/600 or 2/3
