Πιθανότητες

(Ελληνικά)

Η θεωρία πιθανοτήτων (αγγλικάProbability Theory) είναι μια αξιωματική μαθηματική θεωρία μέτρου. Πρόκειται δηλαδή για τον κλάδο των μαθηματικών ο οποίος ασχολείται με την ανάλυση τυχαίων φαινομένων. Κεντρικό ρόλο στη θεωρία πιθανοτήτων παίζει η έννοια της πιθανότητας, ενώ σημαντικές είναι οι τυχαίες μεταβλητές, οι συναρτήσεις κατανομής, οι στοχαστικές διαδικασίες και τα γεγονότα: μαθηματικές αφαιρέσεις μη ντετερμινιστικώνσυμβάντων τα οποία είτε συμβαίνουν μία φορά είτε εξελίσσονται με το πέρασμα του χρόνου. Η πιθανότητα εκφράζει την αβεβαιότητα του ανθρώπου για την εξέλιξη των φαινομένων. Το μέτρο δε της πιθανότητας ορίστηκε να είναι ένας θετικός αριθμός, μικρότερος ή ίσος του ένα. Αν και τα γεγονότα που μελετώνται από τη θεωρία πιθανοτήτων, όπως π.χ. η ρίψη ενός ζαριού ή το στρίψιμο ενός κέρματος, είναι τυχαία, όταν επαναλαμβάνονται πολλές φορές η αλληλουχία των τυχαίων γεγονότων παρουσιάζει ορισμένα στατιστικά μοτίβα τα οποία μπορούν να μελετηθούν και να προβλεφθούν. Δύο αντιπροσωπευτικά μαθηματικά αποτελέσματα που περιγράφουν τέτοια μοτίβα είναι ο νόμος των μεγάλων αριθμών και το θεώρημα κεντρικού ορίου.
