Question

Two balls are drawn from a bag containing 8 grey and 3 blue balls find the chance that they will be both blue

Answer 1

total balls = 11

possibility of blue balls are 3/11

Answer 2

Answer:

The chance that they will be both blue is $\frac{3}{55}$

Step-by-step explanation:

Given : Two balls are drawn from a bag containing 8 grey and 3 blue balls.

To find : The chance that they will be both blue ?

Solution :

Number of grey balls = 8

Number of blue balls = 3

Total number of balls = 11

The chance of getting first ball blue is $\frac{3}{11}$

The chance of getting second ball blue is  $\frac{2}{10}$

The chance that they will be both blue is

$P=\frac{3}{11}\times \frac{2}{10}$

$P=\frac{3}{55}$

Therefore, The chance that they will be both blue is $\frac{3}{55}$
