EXPLANATION.
A bag containing 10 black and 12 whit balls.
A ball is drawn at random.
As we know that,
Total number of balls = 10 + 12 = 22.
Number of black balls = 10.
Number of white balls = 12.
Probability = Number of Favorable outcomes/Number of possible outcomes.
Probability that it is black = 10/22 = 5/11.

From a bag containing 10 black and 12 white balls, a ball is drawn
at random.
To Find :-
Probability of getting black
Solution :-
We know that
Probability = Favourable outcome/Total number of outcomes
Total outcomes = Black balls + White balls
Total outcomes = 10 + 12
Total outcomes = 22
Probability = 10/22
