There are 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 chosen from a bag randomly. What is the probability that the flower chosen is pink?
A) 4/9 B) 1/3 C) 5/9 D) 3/9 E) 2/7
Read Solution (Total 2)
-
- Bag A= 6 red+ 3 pink flowers
Bag B=2 red + 7 pink flowers
probability of picking 1 pink flower from Bag A= 3/9
probability of picking 1 pink flower from Bag B= 7/9
Total = 3/9 + 7/9= 10/9
and probability of selecting a bag is 1/2
so, finally probability of choosing a pink flower= 1/2(10/9) = 5/9 - 4 years agoHelpfull: Yes(4) No(0)
- Bag A
Red flowers = 6
Pink flowers = 3
Bag B
Red flowers = 2
Pink flowers = 7
Total flowers in both bags = 6+3+2+7=18
Total pink flowers = 3+7=10
The probability that the flower chosen is pink = no of pink flower/total no of flower
=
= 10/18
Hence The probability that the flower chosen is pink is 5/9 - 3 years agoHelpfull: Yes(0) No(0)
