Mutually Exclusive Events- Two or more events events are said to be mutually exclusive if only one can happen at a time. Example-1 In tossing a coin, event of tail up (T) and even of heads up (H) can not Read more…
Linear Independence of Vectors Suppose α1, α2, α3, α4…………αn are vectors of V(F) where F is field. And there exist scalers a1, a2, a3, a4………..an which belong to field F. α1, α2, α3, α4…………αn vectors are called lineary independent if Read more…
Chi-Square is a statistical tool but, it is used as parametric and non-parametric both ways. It is a statistic such as, used in different fields where we use it statistic like as, 1- Independent of two attributes. 2- Goodness of fit. a Read more…
A function f(z) which is defined in D and single valued differentiable for all points of D is said to be analytic function of z in domain D. Necessary condition a complex function to be analytic and Cauchy- Riemann equations. A Read more…
