let X is number of heads which follows binomial distribution with parameter n=7 and p=1/2
P(at most 3 heads)=P(X<=3)=P(X=0)+P(X=1)+P(X=2)+P(X=3)
=7C0(1/2)0(1/2)7+7C1(1/2)1(1/2)6+7C2(1/2)2(1/2)5+7C3(1/2)3(1/2)4
=0.0078+0.0547+0.1641+0.2734=0.5
hence P(1 heads given at most 3 heads)=P(X=1|X<=3)=P(X=1)/P(X<=3)=0.0547/0.5=0.1094

MATLAB
Notes: B)
Find likelihood for each sequence 1-9 for each
hypothesis.
First hypothesis with the fair coin (theta value = 0.5): what
is the probability that we can get each sequence, 1 through
9.
Second hypothesis with weighted coin(don’t know theta value):
what is likelihood of getting sequence 1 through 9. Using equation
to find all possible hundred theta values. For each theta value we
need to compute likelihood.
Then we sum them up across all possible theta values....

6. [R Programming| In order to complete this question, we will need to use a fundamen- tal theorem in probabilty theory known as the (Weak) Law of Large Numbers (WLLN) The WLLN will be covered in greater detail in Chapter 8, however we will use this key result throughout the course to approximate probabilities that are otherwise difficult to calculate theoretically. A simplified version of the theorem goes as follows. Assume we are interested in com- puting the probability of...

A. Issues [1] In addition to damages for one year's notice period, can a trial judge award significant damages for the mere fact of an employee's dismissal, or for the stigma that that dismissal brings? Or for the employer thereafter competing with the ex-employee for the clients, before the ex-employee has got a new job? B. Basic Facts [2] This is an appeal from 2009 ABQB 591 (CanLII), 473 A.R. 254. [3] Usually a judgment recites facts before law. But...
