There ara two bags A and B. A contains 6 red flowers and 3 pink flowers. where as bag B contains 2 red flowers and 7 pink flowers. One flower is choosen from a bag randomly. What is the probability that the flower choosen is pink?

a.4/9
b.1/3
c.5/4
d.3/9

• bag A-6 red+3 pink
  bag B-2 red+7 pink
  probability of picking 1 pink from bag A is-3/9
  probability of picking 1 pink from bag B is-7/9
  Total =3/9+7/9=10/9
  and probability of selecting a bag is-1/2
  so finally prob. of choosing a pink flower=1/2(10/9)=5/9

• probability of pink ball=((1/2)*3/9)+((1/2)*7/9)=5/9

• simply, the question says , the work is done in 4*3 = 12 man working hours
  so, if 4 people do it, then no. of days required = 12/4 = 3 (answer)

• Total number of flowers in bag A = 6+3 = 9.
  Total number of flowers in bag B = 7+2 = 9.
  Probability of choosing any one of the bags= 1/2.
  
  Probability of choosing a pink flower from bag A
  = No. of Pink flowers in Bag A / total number of flowers in Bag A.
  = 3/9.
  
  Probability of choosing a pink flower from bag B
  = No. of Pink flowers in Bag B/ total number of flowers in Bag B.
  = 7/9.
  
  Probability of choosing a pink flower at random
  = (Probability of choosing Bag A * Probability of choosing a pink flower from bag A) +
  (Probability of choosing Bag B * Probability of choosing a pink flower from bag B)
  = (1/2 * 3/9) + (1/2 * 7/9)
  = 3/18 + 7/18
  = 10/18
  =5/9.
  
  Hence, the probability of choosing a pink flower from any one of the bags at random is 5/9.
