Question

2) A bag contains 6 black and 8 white marbles. One marble is drawn at random.What is the probability that the marble drawn is black? *

Answer 1

The Probablity is calculated as

`P(b)=\frac{b}{\text{total}}`

Here P(b) is the probablity of black marble and b is the number of black marbles. So

`P(b)=(6)/(6+8)=(6)/(14)=(3)/(7)`

So out of the seven balls drawn, three will be black.
