एक थैले में 18 लाल 12 नीली और 6 हरी गेंदें हैं तो लाल गेंद न निकलने की प्रायिकता क्या है?

Show answer and explanation
Correct Answer

A. 1/2 / 1/2

Explanation

There are 36 balls and 18 are not red so the probability is 18/36 = 1/2.

कुल गेंदें 36 हैं और लाल नहीं होने वाली गेंदें 18 हैं इसलिए प्रायिकता 18/36 = 1/2 है।
