extra credit problem - solution
theorem: if two random variables X and Y have correlation coefficient 1
then one is an affine transform of the other.

Proof: ( , extra credit +5)
reference: Larsen and Max, An Introduction to Mathematical Statistics and its Applications (Chapter 10)

rho(X,Y)= COV(X,Y)/(sigma(X)sigma(Y)) = COV(X*, Y*)
where
X* = (X- mu(X))/sigma(X), and
Y* = (Y- mu(Y))/sigma(Y).

Consider
Var(X*  - Y*) = Var(X*) - 2 COV(X*, Y*) + Var(Y*)
             = 2(1 - COV(X*,Y*))
             = 2(1 - rho(X*,Y*))
             = 0

We have proved earlier that
if a random variable has variance 0, then it must be a constant(determinstic).

Therefore,
X* - Y* = c for some constant c.

therefore,
Y* =  X* - c

therefore,
Y is an affine transform of X.

The case where rho(X,Y)=-1 is similar.

QED.

: 5 18() ð ۽ ( 3) --

1. (BIRTHDAY MATCH) What is the least number of persons required if the probability exceeds 1/2 that two or more of them have the same birthday ? (Year of birth need not match, and February 29 is excluded as a possible birthday.)

2. (CLIFF HANGER) From where he stands, one step toward the cliff would send the drunken man over the edge. He takes random steps, either toward or away from the cliff. At any step his probability of taking a step away is 2/3, of a step toward the cliff 1/3. What is his chance of escaping the cliff ?

2-1. Generalize the above problem to the case where 2/3 and 1/3 are replaced with p and q=1-p for 0<p<1, and the man initially stands at m steps away from the cliff.

3. (GAMBLER'S RUIN) Player M has $1, and Player N has $2. Each play gives one of the players $1 from the other. Player M is enough better than Player N that he wins 2/3 of the plays. They play until one is bankrupt. What is the chance that Player M wins ?

3-1. Generalize the above problem to the case where 2/3 is replaced with p, 0<p<1, and Player M has m dollars and Player N has n dollars.

Enjoy yourself....
