Answer 2

$\huge \bold {\mathfrak {hey}}$
$\bold {\boxed {GIVEN :}}$

✔️ A bag contains white balls = 12
✔️ A bag contains black balls = 18

$\bold {\boxed {To \: Find}}$

Probability of black and white balls

Now,

Total number of balls = 12 + 18 = 30

Formula to find probability is

➡️ P = number of frequency / total number of balls

Now,

Probability of white balls = 12/ 30

Which both are on the table of 6 therefore,

Probability = 2 / 5

Now,

Probability of black balls = 18 / 30

Both are cutted on table of 6

Therefore,
Probability = 3 / 5

So,

The probability of white balls = 2/ 5

The probability of black balls = 3 / 5
