a. To modify the table location to include a column TotalFees having datatype as currency and create and run totals query on condounit table to get total fees by location and update the location table with these values manually.
b.
To create and check data macro for the after-insert event in the CondoUnit table to include the value of added condo fee in new record to the total fees in location table whenever there is insertion of new record in CondoUnit table.
c.
To create and check data macro for the after-update event in the CondoUnit table to add the difference between new condo fee and old condo fee to the total fees for the appropriate location.
d.
To create and check data macro for the after-delete event in the CondoUnit table to subtract the condo fee from the total fees for the appropriate location when deleting a row in the CondoUnit table.

- od The probability mass function of a discrete random variable X is given by P(X = 1) = {} x=1,2,3,4 10 otherwise (a) Draw the probability mass function (PMF) of this random variable. (b) Draw the cumulative distribution function (CDF) of this random variable. (c) What is P{2< x <4}? Write it in terms of the CDF. (d) What is E[X]? (e) What is Var[X]? (f) What is E[X (6-X)]? (g) What is Var[3X - 2]?arrow_forwardOn a multiple-choice exam, there are 4 possible answers for each of the 6 questions. If a student answers the questions by random guesses, (a) What is the probability that he would get exactly 3 correct answers? (b) What is the probability that he would get at least 1 correct answer? (c) If this problem is solved using a binomial random variable, what would the binomial parameters be?arrow_forwardWhat is the difference between diode clipping and clamping circuits?arrow_forward
