Suppose , On Studying the sample of 10000 random profiles in FB , the count of friends is found as ~N( a1,v1).
Suppose , On Studying the sample of 10000 random profiles in FB , the count of friends is found as ~N( a1,v1).
For any profile , the % distribution of friends from the same county follows ~N(a2,v2)
1 What sort of distribution would the count of mutual friends of two random profiles would follow ?
2 What sort of distribution would the count of mutual friends would follow , if both the random profiles are from same county?
3 What sort of distribution would the count of mutual friends would follow , if both the random profiles are from different county?
if A sample of 100 pairs for random profiles is taken,
4 what is the probability that no pair would have more than 7 mutual friends ?
5 what is the probability that at least 7 pairs would have more than 0 mutual friends ?
6 what is the probability that at least 7 pairs would have at least 3 mutual friends ?
