Probability Likelihood

Front

What is the probability of rolling a sum of 15 with a pair of dice?

Back

Impossible, as the maximum sum with two dice is 12.

Front

What does it mean when an event has a probability of zero?

Back

It means the event is impossible to happen.

Front

What is the probability of rolling a 7 on a standard 6-sided die?

Back

Zero, as a 7 cannot be rolled on a 6-sided die.

Front

Define 'outcome' in the context of probability.

Back

An outcome is the result of a single trial of an experiment.

Front

What is the probability of rolling an even number on a standard 6-sided die?

Back

There are three even numbers (2, 4, 6), so the probability is 3/6 or 1/2.

Front

What is the probability of spinning an even number on a standard spinner numbered 1 to 6?

Back

50%, as there are three even numbers (2, 4, 6) out of six total numbers.

Front

What is the definition of probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What is the range of probability values?

Back

Probability values range from 0 (impossible event) to 1 (certain event).

Front

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a probability experiment.

Front

What is the difference between independent and dependent events?

Back

Independent events do not affect each other's outcomes, while dependent events do.
