To Find:-
Probability of black balls
Given:-
There are 4 red balls
There are 3 black balls
There are 2 blue balls
Formulae Applied:-
Probability of an event P(E) = No.of outcomes/Total no. of outcomes
Solution:-
Black balls = 3
Total No.of balls = 9
P(black balls) = No.of black balls/Total No.of balls
P(black balls) = 3/9 = 1/3
Therefore,
The probability of black balls is 1/3.
More Information:-
➝ The probability of an event is calculated by the number of outcomes divided by the total number of outcomes.
➝ The probability of possible event is 1.
➝ Probability of impossible event is 0.
