Tom and Victoria are two children who live in Canada. Consider the following de ned events
about two Canadian cities far from each other: Toronto and Vancouver.
 Let T represent the event that Tom lives in Toronto.
 Let V represent the event that Victoria lives in Vancouver.
1. If Tom and Victoria are any two children in Canada, the events T and V are (check all
that are true):
A) Independent
B) Mutually Exclusive
C) Neither


2. If Tom and Victoria are siblings who live in the same house, the events T and V are
(check all that are true):
A) Independent
B) Mutually Exclusive
C) Neither

if you can put it into a good explanation that would help a lot, thanks.

What do you think the answers are?

Independent means: if you know that T is true, then this still gives you no information about whether V is true
For example: if T is "It rains today" and if V is "a child will be born today". If you know that T is true, that gives you no information about V at all.

mutually exclusive means: if you know T is true, then V can not be true.
For example: if T is "it rains today" and V is "it will be sunny all day".

I will pick Independant for the first one, then 2nd question i will pick mutually exclusive?
 
Yes, that is correct!

Hi all, I've been a roulette player for more than 10 years (although I took time off here and there) and it's only now that I'm trying to understand the physics of the game. Basically my strategy in roulette is to divide the wheel roughly into two halves (let's call them A and B). My theory is that in roulette there will invariably be variance. In other words, if A comes up 5 times in a row, B will be due to come up soon. However I have been proven wrong many times, and I have seen some...
Thread 'Detail of Diagonalization Lemma'
The following is more or less taken from page 6 of C. Smorynski's "Self-Reference and Modal Logic". (Springer, 1985) (I couldn't get raised brackets to indicate codification (Gödel numbering), so I use a box. The overline is assigning a name. The detail I would like clarification on is in the second step in the last line, where we have an m-overlined, and we substitute the expression for m. Are we saying that the name of a coded term is the same as the coded term? Thanks in advance.
