The probability of selecting girl is: 25/100 = 1/4
The probability of selecting rich is: 20/100 = 1/5
The probability of selecting fair complexioned is: 40/100 = 2/5
Three are independent:
So, probability of rich and fair complexioned girl is = (1/4) *(1/5)* (2/5) = 1/50

89. 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?

| | Important Formulas | Topic: | Asked In |

Explanation:

Given Bag A contain 6 red & 3 pink => total ball = 9
Bag B contain 2 red & 7 pink => total ball = 9
Probability of picking 1 pink from bag A = 3/9
Probability of picking 1 pink from bag B = 7/9
Total = 3/9 + 7/9 = 10/9
And probability of selecting a bag is 1/2
So, probability of choosing a pink flower = [(1/2)* (10/9)] = 5/9
