There are 3 balls in a black box – one is white, and the other two are black, what is the probability

There are 3 balls in a black box – one is white, and the other two are black, what is the probability that the first to pull the black ball, and the second white

1) total 3 balls of different colors
To find the probability that the black ball will be drawn first, you need to divide the number of black balls by the total number of balls, i.e. we get:
2/3 is the probability that the black ball will be drawn first

2) to find the probability that the white ball will be drawn second, we already take 2 balls (we have one white and one black). Divide one white ball by the total number of remaining balls. That is, we get
1/2 is the probability that the white ball will be drawn second

3) Now we will find the probability of the entire specified event
(2/3) * (1/2) = 1/3.

Answer: 1/3
