Question

the probability of selecting a blue ball at random from a jar that contains glue green and yellow balls is 1/3 the
probability of selecting a green ball at random from the same jar is 2/9 1000 contains 16 yellow balls find the total number of balls in the jar​

Answer 1

Answer:

Explanation:

Let total number of  balls in jar =x

Then number of blue balls in jar =  

3

1

​  

x=  

3

x

​  

 

And number of red balls =  

4

1

​  

x=  

4

x

​  

 

And number of orange balls =10 (given)

∴x=  

3

x

​  

+  

4

x

​  

+10

⇒12x=3x+4x+120

⇒12x−7x=120

⇒5x=120

⇒x=24

Then total balls in jar is 24.
