Question

1 8 If two events (both with probability greater than O) are mutually exclusive, 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) b. Partition c. Ordinal d. Permutation 2 , if two events are independent, then a. b. C. d. They must be mutually exclusive The sum of their probabilities must be equal to one Their intersection must be zero None of these alternatives is correct POSSIBLY USEFUL FORMULAS Binomia! pty-()p-p) =(x + r: 1)r(1-p)" pfx)- Poisson plx)-

Explanation / Answer

18.Mutually exclusive means the two events doesn't share a common element across their sample space. And as such If we label two events as A and B, P(A and B) =o but P(A). P(B) is not equal to zero. Hence, the condition for independence is not met. Option C

19. Permutation

20. Option d
