☕️ Morning coffee session Today's quiz is the following: On a TV show you have 3 doors. Behind one of the three there is an expensive car. Behind the other two there are goats. You initially choose door 1. Then the TV presenter of the show opens door 3…
Our today quiz is The Monty Hall problem. It is a brain teaser, in the form of a probability puzzle, loosely based on the American television game show Let's Make a Deal and named after its original host, Monty Hall.
Check the spoiler to see the answer.
The correct answer is to switch to the other door n2. Under the standard assumptions, the switching strategy has a 2/3 probability of winning the car, while the strategy that remains with the initial choice n1 has only a 1/3 probability.
When the player first makes their choice n1, there is a 2/3 chance that the car is behind one of the doors he did not chose. This probability does not change after the host reveals a goat behind one of the unchosen doors n3. When the host provides information about the 2 unchosen doors (revealing that one of them does not have the car behind) the allocation of the winning chances does not change.
So statistically and as proven by computer simulations the player should better change door to increase his chances.

Is Ukraine the 51st state of USA?
Marjorie Taylor Greene means business. The republican representative elected with 66% in Georgia without wasting a single moment brings a resolution demanding to investigate the 54bln $ spent on Ukraine. She questions where the next 38bln$ will go.
This along with the personal investigation started on Biden and his son personal investments in Ukrainian Oil companies and the Ukrainian FTX crypto scandal means next few months will be living hell for the Democrats in USA.

🚨 Ukrainian army yesterday 19th and today 20th November resumed attacks on nuclear power plant in Zaporizia.
Rafael Grossi, Director General of the International Atomic Energy Agency just stated:
"As I have said many times before, you’re playing with fire!”
The plant is under control of Russian soldiers since April.
Ukraine’s army is regularly shelling the industrial area of the Zaporozhiue nuclear power plant, disturbing the energy supplies and other processes on the NPP.
However, they do not always target the dangerous nuclear facilities located in the plant itself as in the case of damage to main facilities, the risk of nuclear catastrophe grows.
Since the end of September, the Armed Forces of Ukraine (AFU) stopped their attacks on the territory of the plant.
Unfortunately, the Ukrainian military has resumed shelling the NPP area, targeting the nuclear facilities, on November 19 & 20.
