Agar main yeh sikka uchhalun, to kya aap pehle se pakka bata sakte hain ki head aayega ya tail? Nahin, ek sikke ka nateeja pehle se pakka nahin jaan sakte. Probability anishchitata ko naapti hai: har nateeje ki sambhavna. Ek fair coin mein do hi barabar-barabar sambhavnayein hain, head ya tail. Isliye kisi ek chune hue nateeje ki sambhavna hai: ek manchaha nateeja, do sambhavit nateejon mein se. Yaani 50%. Lekin 50% agli uchhal ki guarantee nahin: head aur tail baari-baari se aana zaroori nahin. Har uchhal mein dono ke chances barabar hain. Ek uchhal aapko chaunka sakti hai. Kai uchhalon mein parinaam aksar in chances ke kareeb dikhte hain, phir bhi har uchhal anishchit rahti hai. To sawaal ka jawaab? Nahin, flip ka nateeja pakka nahin bata sakte, probability bas batati hai ki head ya tail aane ki kitni sambhavna hai.
