Question

Hi there, I have an exam on the 17th May at 12:00 Midday (GMT). It is a 2 hour probability (University Level) exam and was wondering if TAE provides a service which can solve the answers within a 2 hour period.
Perfect, the layout of the exam is to answer 3 out of the 4 questions. We have 2 hours to do the exam. On the day the exam questions are released, I can send these over to TAE and will they be able to get the answers done (with working out) within an hour and a half?
I have uploaded exam questions from 3 papers.

The event space F is the set of all distinct possible outcomes of the random process. Event space sometimes called sample space contains distinct outcomes and also these exhaust all the possibilities
If we write prob for all elements in the event space, the sum of all probabilities would always be equal to 1.
A and B are two possible outcomes in event space F. A\B, the symmetric difference of A and B is nothing but all outcomes in event A but not in B.  In Venn diagram this would be denoted as A-B or A-A intersectin B
Since A and B are in the set F, A-B being a proper subset of A also must belong to F
Standard event space F would be sets A,B,C,D… which are distinct and disjoint.  These if grouped would be exhaustive of F
F={A,B,,..} which are disjoint mutually exclusive but exhaustive of F
For example, when we toss a die, the events are 
{1,2,3,4,5,6} the outcomes and form a std event space
A – it snows on Monday
B – it snows on Tuesday
Prob that it snows atleast on Monday or Tuesday 
=P(AUB) = P(A)+P(B)-P(A⊓B)
= 0.75+0.50-0.40 = 0.80
P(A⊓B)=0.40
P(A)*P(B) = 0.75*0.50 = 0.
