Multiple Choice Question Explain IF possible! I will leave thumbs up :)

If two events (both with probability greater than 0} are mutually ex probability greater than o are mutually exclusive, then: a. They also must be independent b. They also could be independent C. They cannot be independent d. They must be exhaustive A selection in which order DOES matter is called a(n) - a. Combination b. Partition Ordinal d. Permutation 2. If two events are independent, then a. They must be mutually exclusive b. The sum of their probabilities must be equal to one CTheir intersection must be zero d. None of these alternatives is correct POSSIBLY USEFUL FORMULAS Binomial P(x) = (*) p(1-p)"-* E(X) = np, V(X) = npq Negative Binomial p(x) = (*#:; ')Pr(-p)* E(X) = 711-72vix) = Hypergeometric pos.

Explanation / Answer

Q18) Option C is Correct, They can't be independent because in mutually exclusve probailities of P( A and B ) will be zero

Q19) Option D is Correct. In Permutation order is matter.

Q20) Option D is Correct.
