Question

A bag contains 10 white as well as Black balls a person draws 6 balls and finds that three balls are white and other three are black find the probability that the number of white balls in the bag is same as as the number of black balls.

Answer 1

Answer:

probability of getting white ball=10/20=1/2

probability of getting a black ball=10/20=1/2

Answer 2

Concept

Probability of certain event is occurrence of that particular event out of the total possibility of events. The probability is equal to the variety of possible outcomes. the total number of outcomes that might occur. For instance, there is only one method to receive a head and there are a total of two possible outcomes, hence the chance of flipping a coin and receiving heads is $1$ in $2$. (a head or tail). P(heads) = $12$ is what we write.

Given

A bag contains $10$ white as well as Black balls a person draws $6$ balls and finds that three balls are white and other three are black.

To Find

We have to find the number of white and black balls in the bag.

Solution

According to the problem,

The probability of picking the white and black ball is same as three out of six.

Hence the probability of drawing black and white ball is $1/2$.
