Question

Q35)A bag contains 5 red balls and some blue balls. If the probability of drawing a blue ball is double that

of a red ball, determine the number of blue balls in the bag.​

Answer 1

Answer:

10

Step-by-step explanation:

P(blue ball) = 2*P(red ball)

No. of blue balls/Total number of balls= 2*No. of red balls/Total number of balls

No. of blue balls= 2*No. of red balls [Total no. of balls get cut from both side]

No. of blue balls= 2*5

= 10
