A bag has 15 red 10 blue and 5 green balls. What is the probability of not drawing a red ball?

एक थैले में 15 लाल 10 नीली और 5 हरी गेंदें हैं तो लाल गेंद न निकलने की प्रायिकता क्या है?

A 1/3 / 1/3 B 1/2 / 1/2 C 2/3 / 2/3 D 5/6 / 5/6
Show answer and explanation
Correct Answer

B. 1/2 / 1/2

Explanation

There are 30 balls and 15 are not red so the probability is 15/30 = 1/2.

कुल गेंदें 30 हैं और लाल नहीं होने वाली गेंदें 15 हैं इसलिए प्रायिकता 15/30 = 1/2 है।
