Question

A bag contains 12 balls of blue and red colour in that number of blue balls are twice to red balls then find the probability to pick up each ball . answer fast

Answer 1

Answer:

here is ur answer

Step-by-step explanation:

Let number of red balls = x

Probability of selecting one red ball = P1=x12

If the number of red balls increased by 6 , total number of balls = 18

Probability of selecting one red ball = P2=x+618

Given: P2=2∗P1⟹x+618=2∗x12

⟹6(x+6)=18x⟹x=3
