Online Statistics Probability MCQs 2

These are MCQs 2 on "PROBABILITY"

1. The outcome of tossing a coin is a:

• Mutually exclusive event
• Compound event
• Certain event
• Simple event

2. The result of no interest of an experiment is called:

• Constant
• Event
• Failure
• Success

3. A set of all possible outcomes of an experiment is called:

• Combination
• Sample point
• Sample space
• Compound event

4. The numbers of counting rules that are useful in determining the number of outcomes in an experiment are:

• One
• Two
• Three
• Four

5. The events having no experimental outcomes in common is called:

• Equally likely events
• Exhaustive events
• Mutually exclusive events
• Independent events

6. A set of outcomes formed after some additional information is called:

• Sample space
• Reduced sample space
• Null set
• Random experiment

7. The probability associated with the reduced sample space is called:

• Conditional probability
• Statistical probability
• Mathematical probability
• Subjective probability

8. An arrangement of objects without regard to order is called:

• Permutation
• Combination
• Random experiment
• Sample point

9. The number of permutations of a set of n things, taken r at a time with n 2 r given by:

• n! / (n-r)!
• n! / (r-n)!
• n! / r!(n-r)!
• n! / r!

10. If three candidates are selected to attend a course from the ten candidates, the number of ways of selecting the candidates is an example of:

• Combination
• Permutation
• Reduced sample space
• Both (a) and (b)
