An article appeared in the Journal of Gambling Issues, in which the authors looked at random samples of Ontario residents who (i) have not completed some form of post-secondary education and
(ii) have completed some form of post-secondary education.
A code of 0 indicates the person does not have a gambling problem, a code of 1 indicates the person does have a gambling problem.
The data is found in the accompanying data file.

To count the frequencies of 0 and 1 in each sample, use the table(your_dataset_name$ column's name) function. Make sure to replace "your_dataset_name" with the actual name of your data file
and specify the correct column name.
For example: table(file60c5d1286c735$ CompletedPSEducation)
Let PNOPS represent the proportion of persons not completing some form of post-secondary education who have a gambling problem, and
PPs be the proportion of persons having completed post-secondary education who have a gambling problem.

We consider a (European) call option on a stock with expiration in 3 months and strike
price $10. The annual interest rate on the market is r = 4%. The current price of the stock
is $10 and we assume that the stock follows a geometric Brownian motion (Black-Scholes)
model with parameters = 6% and σ = 0.2.
(a) Determine the price Fo of this option at time t
=
: 0 (today).
(b) Using the formulas provided in the lecture videos, calculate the value of each of the
Greeks for this option. Namely, calculate A, T, v, О, p.

(d) For each of the suggested modifications below, use an approximation to determine
the change in the price of the option above without actually recalculating the price.
For each one, provide an intuitive argument to explain why the price increases or
decreases.

A box containing 24 seemly identical resistors has just been received. However,unbeknownst, 4 of these resistors are defective.
a. Five resistors are randomly selected from this box without replacement (oncemoved from the box it is not returned to the box), what is the probability that oneor more of the defective resistors is among those selected?
b. Five resistors are randomly selected from this box with replacement (after theresistor is removed and checked, it is returned to the box prior to the nextselection (hence the same resistor can be selected more than once)), what is theprobability that one or more of the defective resistors is among those selected?
