Question

a box contains 6 black balls and 4 white balls .what is the probability of getting a white ball?​

Answer 1

Given :

• A box contains 6 black balls and 4 white balls.

To Find :

• Probability of getting a white ball .

Solution :

$\longmapsto\tt{Black\:Balls=6}$

$\longmapsto\tt{White\:Balls=4}$

$\longmapsto\tt{Total\:Balls=10}$

Now ,

$\longmapsto\tt{Favourable\:Outcomes=4}$

$\longmapsto\tt\bf{Probability=\frac{No.\:of\:Fav.\:Outcomes}{Total\:No.\:of\:Outcomes}}$

$\longmapsto\tt{\cancel\dfrac{4}{10}}$

$\longmapsto\tt\bf{\dfrac{2}{5}}$

So , The Probability of getting a white ball is 2/5 ...
