2. In probability, it is common to model the deviation of a day's temperature from the monthly
average temperature using the Gaussian probability density function,
f(t) =
This means that the probability that the day's temperature will be between t = a and t = b
different from the monthly average temperature is given by the area under the graph of
y = f(t) between t = a and t = b.
A related function is

F(1) =
e2/9 dt, r20.
This function gives the probability that the day's temperature is between t = -x and t = r
different from the monthly average temperature. For example, F(1) = (0.36 indicates that
there's roughly a 36% chance that the day's temperature will be within 1 degree (between 1
degree less and 1 degree more) of the monthly average.

(a) Find a power series representation of F(r) (write down the power series using sigma
notation).
(b) Use your answer to (a) to find a series equal to the probability that the day's temperature
will be within 2 degrees of the monthly average.…
With the known values of a = 200,000 and b = 230,000, the first equation for the probability density function for the sales price of a home is found as follows.
f(x) = 1/b – a, a ≤ x ≤ b
= 1/230,000 − 200000, 200,000 ≤ x ≤ 230,000
= 1/30000, 200,000 ≤ x ≤ 230,000
Everywhere else, the probability density function will just be 0. Therefore, the full probability density function for the sales price of a home follows.
