Probability Quiz

What is a sample space in probability?

• The sample space is the set of all possible outcomes of a predetermined experiment or process.

• The sample space is the set of all impossible outcomes of a random experiment or process.

• The sample space is the set of all possible outcomes of a controlled experiment or process.

• The sample space is the set of all possible outcomes of a random experiment or process.

Define an event in the context of probability.

• Specific outcome or set of outcomes of a random experiment

• An event that is not related to probability

• A predetermined outcome of a random experiment

• A random experiment with no specific outcome

What is the formula to calculate probability?

• Probability = Number of favorable outcomes

• Probability = Number of favorable outcomes / Total number of possible outcomes

• Probability = Total number of possible outcomes

• Probability = Number of favorable outcomes + Total number of possible outcomes

What is experimental probability?

• Experimental probability is the probability obtained through conducting experiments or trials and recording the outcomes.

• Experimental probability is the probability obtained by using mathematical formulas and calculations.

• Experimental probability is the probability obtained by guessing the outcome without conducting any experiments.

• Experimental probability is the probability obtained by asking people for their opinions and predictions.

What is theoretical probability?

• Branch of mathematics dealing with the likelihood of an event occurring based on mathematical reasoning and assumptions.

• Theoretical probability is the likelihood of an event occurring based on personal beliefs and opinions.

• Theoretical probability is the study of the likelihood of an event occurring based on historical data and trends.

• Theoretical probability is the calculation of the likelihood of an event occurring based on experimental trials and observations.
