1. The set of all possible outcomes of en experiment is called the ------.

a) samples space b) With replacement c) without replacement

2. If sampling is conducted ------------- then the sample space for the probability involving the second selection is one less than the first.

a) samples space b) With replacement c) without replacement

3. The theory of probability sometimes is called the mathematics of_________________ ( fill in the blank)

4.The expression P(A or B) = P(A) + P(B) is valid if:

a) A and B are independent

b) A and B are dependent

c) A and B are mutually exclusive

5. Two probability can be multiplied when we are asked:

a) an 'or' question and the events are independent

b) an 'or' question and the events are mutually exclusive

c) an 'and' question and the events are independent

d) an 'and' question and the events are mutually exclusive

Explanation / Answer

1. The set of all possible outcomes of en experiment is called the ------.

a) samples space

2. If sampling is conducted ----- c) without replacement-------- then the sample space for the probability involving the second selection is one less than the first.

4.The expression P(A or B) = P(A) + P(B) is valid if: c) A and B are mutually exclusive because then only P(A and B)=0 that is the two events can not occur simultaneously.

5. Two probability can be multiplied when we are asked:

c) an 'and' question and the events are independent

That is P(A and B)=P(A)*P(B) iff A and B are independent of each other.
