Question

If 'x' Red balls are shifted from bag A to bag C the probability of green ball from Bag C is reduced by 1/12 find the value of X.

Answer 1

Answer:

x = T²/(12G - T)

Step-by-step explanation:

Let say Bag C  has  

G  Green Balls

& T - Total Balls

Probability of Green Balls = G/T

x Red balls are shifted from bag A to bag C

=> Bag C Total Balls  =  T + x

Probability =  G/(T + x)

G/(T + x)  = G/T  - 1/12

=> 12G T  = 12G ( T + x)  - T (T + x)

=> T² + Tx - 12Gx  = 0

=> T ² - x(12G - T) = 0

=> x = T²/(12G - T)
