Probability is measured on a scale from 0 to 1. A probability of 0 means impossible, a probability of 1 means certain, and most event probabilities lie strictly between 0 and 1.
प्रायिकता का पैमाना क्या है?
Answer
प्रायिकता को 0 से 1 तक के पैमाने पर मापा जाता है। 0 की प्रायिकता का अर्थ असंभव है, 1 की प्रायिकता का अर्थ निश्चित है, और अधिकांश घटनाओं की प्रायिकताएँ 0 और 1 के बीच सख्ती से होती हैं।…
