Question

There is a bag which contains 50 balls of same size. 20 of those balls are red in colour and remaining 30 are white. Now, if you take a ball out from the bag what can be said about its colour?

• A. It must be red
• B. It must be white
• C. May be red or white
• D. Getting a red ball and getting white ball are two equally likely outcomes

Answer 1

The correct option is C

May be red or white

The withdrawn ball may be of red colour or white colour. Since white balls are 30 in number, it is more likely that withdrawn ball will be white incolour. Similarly, it is less likely that ball will be red. We can never be sure that withdrawn ball is of red or white unless all the balls are of same colour.
