A bag contains 5 red balls and some blue balls .if the probability of drawing a blue ball from the bag is thrice that of a red balls in the bags.



The Brainliest Answer!
No. of red balls = 5 .
Therefore the no of blue balls = 3×5=15
Total no. of outcomes =5+15=20.
Probability of getting blue balls P(E)=15/20=3/4.
2 5 2
No. of red balls=5
Let no. of blue balls be x
Total balls=5+x
according to question,
x/5+x = 3 X 5/x+5
no. of blue balls=15
P(of blue ball)=15/20=3/4
