Question

A bag contains 5 red balls and some blue balls if the probability of draning a blue ball is double that of a red ball then the number of blue ball in a bag is
​

Answer 1

Step-by-step explanation:

let the no. of blue ball in the bag =x

total no. of blue ball in the bag =5+x (no. of red balls =5)

probability of drawing a blue ball =

no.of blue ball/total no. of. ball

p (B)= x/5+x

probability of drawing a red ball=

no.of red ball/total no. of ball

p (R)= 5/5+x

p (B)=2p (R)

x/5+x= 2 (x/5+x)

x=10

therefore no. of blue balls =10 .
