Question

There are total 20 balls out of which 12 are red and 8 are white if one ball at random find the probability that ball picked is white ball​

Answer 1

Here is the correct answer:-

The box contains 20 balls

12- red 8-blue

Probability of drawing red ball is 12/20

Probability of drawing blue ball is 8/19 ( without replacement)

Probability of drawing red ball in first draw & blue in second draw = 12/20 *

8/19

Probability of drawing blue ball in first draw & red ball in second draw = 8/20

*12 /19

Total probability= 12/20 * 8/19 * 8/20 * 12/19= 0.505 ans

Hence the correct answer is 0.505

Hope this helps you ❤️

Answer 2

Answer:

Hey mate your answer is as follows

Total balls= 20

Out of which 12 are red and 8 are white

then

$probability \: of \: getting \: white \: ball \: is \: \frac{8}{20} = \frac{2}{5}$

Hope it helps you
