Card 5यादृच्छिक घटनाएँ

सिक्का उछालना और पासा फेंकना यादृच्छिक घटनाएँ क्यों कहलाती हैं?

Answer

इन्हें यादृच्छिक इसलिए कहा जाता है क्योंकि क्रिया होने से पहले सटीक परिणाम की भविष्यवाणी नहीं की जा सकती। सिक्के में हेड्स या टेल्स आ सकते हैं, और पासे में 1 से 6 तक कोई भी संख्या आ सकती है। संभावित प

Card 6Random events

Why are tossing a coin and rolling a die called random events?

They are random because the exact result cannot be predicted before the action happens. A coin can show heads or tails, and a die can show 1 to 6. The possible outcomes are known, but the one that wil

Card 7Probability scale

What is the probability scale?

Answer

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.

Card 8प्रायिकता पैमाना

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।
