Final answer:
The probability density function for the sales price of a house is given by f(x) = 1/(b - a) for a <= x <= b, and 0 elsewhere. In this case, a = 200,000 and b = 230,000.
Step-by-step explanation:
The probability density function for the sales price of a house is given by the equation:
f(x) = 1/(b - a) for a <= x <= b, and 0 elsewhere.
In this case, the random variable x represents the sales price of the house, which is uniformly distributed between $200,000 and $230,000. Therefore, a = 200,000 and b = 230,000.
