Probability means how likely an event can occur and conditional probability is how likely an event can occur given another event has already occurred. There is a dependence between the events. P(B/A) = P(A,B)/P(A) P(B/A) - Probability of B given A P(A,B) - Probability of both B and A P(A) - Probability of A For … Continue reading Conditional Probability

Covariance And Correlation
Covariance It gives relation between two features or two random variables. It tells how one depends upon other. It could be positive or negative. Simple way to find covariance is to multiple variance of both the variables. Let's discuss this with an example then it will be more clear. Let a = [1,2,3,4,5,6,7,8,9] and b … Continue reading Covariance And Correlation
