For a Binomial distribution B (n, p),E(x)/V(x)is is equal to: (symbols have their usual meaning)
Correct Answer :
1/1-P
Solution :
The correct option is 1/1-P.
Let us understand the step-by-step derivation for the ratio of the expectation to the variance of a Binomial distribution, denoted as B(n, p).
For a Binomial distribution with parameters n (number of trials) and p (probability of success):
1. The expected value or mean, denoted as E(x), is given by:
Now, we find the ratio of E(x) to V(x):
