in a subdivision, 67 perecent of the homes have detached garages, 32 perecent have a patio, and 13 percent have both. What is the probability that a house has a patio if you know that it has a detached garage?
would it be 32/67?
Good guess. Only 13% have BOTH, so it is actually 13/67.
If 13% (.13) have both detached garages and patios, isn't that the probability?
Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.
