Online Statistics Probability MCQs 3

These are MCQs 3 on "PROBABILITY"

1. When each outcome of a sample space is as likely to occur as any other, the outcomes are called:

• Exhaustive
• Mutually exclusive
• Equally likely
• Not mutually exclusive

2. If A is any event in S and A its complement, then P(A ) is equal to:

• 1
• 0
• 1- A
• 1 - P(A)

3. When certainty is involved in a situation, its probability is equal to:

• Zero
• Between -l and + 1
• Between 0 and 1
• One

4. Which of the following cannot be taken as probability of an event?

• 0
• 0.5
• 1
• -1

5. If an event contains more than one sample points, it is called a:

• Simple event
• Compound event
• Impossible event
• Certain event

6. When the occurrence of one event has no effect on the probability of the occurrence of another event, the events are called:

• Independent
• Dependent
• Mutually exclusive
• Equally likely

7. A particular result of an experiment is called:

• Trial
• Simple event
• Compound event
• Outcome

8. A collection of one or more outcomes of an experiment is called:

• Event
• Outcome
• Sample point
• None of the above

9. A process that leads to the occurrence of one and only one of several possible observations is called:

• Random experiment
• Random variable
• Experiment
• Probability distribution

10. Which statement is false?

• The classical definition applies when there are n equally likely outcomes to an experiment
• The empirical definition occurs when number of times an event happen is divided by the number of observations.
• A subjective probability is based on whatever information is available
• The general rule of addition is used when the events are mutually exclusive
