WebbProbability is the chance that the variable has a specific value, whereas the probability density is the chance that the variable will be near a specific value, meaning probability over a range. So to obtain the probability you need to compute the integral of the probability density function over a given interval. WebbNotice that the four probabilities add up to 1, as we expect for a probability function. 11.121 Owner-Occupied Housing Units (Graded for Accurateness) In the 2010 US Cen-sus, we learn that 65% of all housing units are owner-occupied while the rest are rented.
