A container contains 3 red and black balls. If one ball is selected at random from the container, what is the probability that it is black

# black balls/ total balls
give me and please
To find the probability of selecting a black ball, we need to know the total number of balls in the container and the number of black balls.
Let's assume that the container contains a total of 3 red and black balls. If we denote the number of black balls as "B," we can start by finding the number of black balls.
Since the total number of balls in the container is 3, the possible values for B are 0, 1, 2, and 3.
To calculate the probability of selecting a black ball, we can divide the number of black balls by the total number of balls:
Probability of selecting a black ball = Number of black balls / Total number of balls
Now, let's calculate the probability for each possible value of B:
1. If there are 0 black balls, then B = 0:
Probability of selecting a black ball = 0 / 3 = 0 (no black balls)
2. If there is 1 black ball, then B = 1:
Probability of selecting a black ball = 1 / 3 = 1/3
3. If there are 2 black balls, then B = 2:
Probability of selecting a black ball = 2 / 3 = 2/3
4. If there are 3 black balls, then B = 3:
Probability of selecting a black ball = 3 / 3 = 1 (all black balls)
So, depending on the number of black balls in the container, the probability of selecting a black ball can be 0, 1/3, 2/3, or 1.
