from a bag containing 4 red and 2 black balls, two balls are drawn the probability of getting 2 black ball is
Answers
Answer:
We assume that there are 4 white balls and 2 black balls.
There are (
2
6
)=15 total possible ways of drawing two balls from these given 6 balls.
We are interested in the event where the two drawn balls are of the same colour.
For this, we note that the number of ways of drawing 2 white balls is (
2
4
)=6 whereas the number of ways of drawing 2 black balls is (
2
2
)=1.
So, the probability that the two drawn balls are of the same colour is
15
6+1
=
15
7
.

Answer:
We assume that there are 4 red balls and 2 black balls.
There are 15 total possible ways of drawing two balls from these given 6 balls.
We are interested in the event where the two drawn balls are of the same color.
For this, we note that the number of ways of drawing 2 red balls is =6 whereas the number of ways of drawing 2 black balls is =1.
So, the probability that the two drawn balls are of the same color is
=6+1/15
=7/15
therefore
probability of getting two black balls is 7/15
