There are 5 white balls and some blue balls in a bag, if the probability of drawing a blue ball is double
the probabaty of drawing a white ball, then remove the probability of a blue ball in the bag 23
The upper surface of a phage will have the numbers 0,1.2,3,4,5 and he will throw the phama twice
If so, find the probability that the multiplication of the digits on the upper surface is
zero. 3) What is the probability that a stray helicopter first falls into a rectangular space as
shown in the figure and falls into the bottom shown in the diagram?
please explain

Answer:
Let number of blue balls in the bag =x
Total no of balls in bag =5+x [No. of white ball =5]
Probability of drawing a blue ball =No. of blue ball/Total no. of ball
P(B)=x/5+x
Probability of drawing a white ball= No of white ball/ total no of ball
P(W)=5/5+x
Given,
P(B)=2P(W)
x/5+x= 2. 5/5+x
X= 10
number of blue balls in the bag is 10
