Online Statistics Probability MCQs 1

These are MCQs 1 on "PROBABILITY"

1. When the possible outcomes of an experiment are equally likely to occur, this we apply:

• Relative probability
• Subjective probability
• Conditional probability
• Classical probability

2. A number between 0 and 1 that is use to measure uncertainty is called:

• Random variable
• Trial
• Simple event
• Probability

3. Probability lies between:

• -1 and +1
• 0 and 1
• 0 and n
• 0 and ∞

4. Probability can be expressed as:

• Ration
• Fraction
• Percentage
• All of the above

5. The probability based on the concept of relative frequency is called:

• Empirical probability
• Statistical probability
• Both (a) and (b)
• Neither (a) nor (b)

6. The probability of an event cannot be:

• Equal to zero
• Greater than zero
• Equal to one
• Less than zero

7. A measure of the chance that an uncertain event will occur:

• An experiment
• An event
• A probability
• A trial

8. A graphical device used to list all possibilities of a sequence of outcomes in systematic way is called:

• Probability histogram
• Venn diagram
• Pie diagram
• Tree diagram

9. A random experiment contains:

• At least one outcome
• At least two outcomes
• At most one outcome
• At most two outcomes

10. The probability of all possible outcomes of a random experiment is always equal to:

• One
• Zero
• Infinity
• All of the above
