MATHS - Statistics - Probability Experiments

The video tutorial introduces the concept of probability, explaining it as a mathematical way to describe the likelihood of events. It covers the probability scale from 0 (impossible) to 1 (certain) and discusses how to distinguish between expected and real outcomes using examples like coin tosses and dice rolls. The tutorial provides a formula for calculating probability and explains how investigations can help determine probabilities through relative frequency. An example of calculating relative frequency with a coin toss is also provided.

What does a probability of 0.5 indicate about an event?

• The event is impossible.

• The event is certain.

• The event is equally likely to occur or not occur.

• The event will definitely not happen.

If you toss a coin, what is the probability of getting heads?

• 1/2

• 1/3

• 1/4

• 1/6

How many possible outcomes are there when rolling a standard six-sided dice?

• 5

• 7

• 4

• 6

What is the relative frequency of getting tails if you toss a coin 10 times and get 6 tails?

• 0.4

• 0.7

• 0.5

• 0.6

Which of the following best describes relative frequency?

• The ratio of the number of successful outcomes to the total number of trials.

• The number of times an event is expected to occur.

• The total number of possible outcomes.

• The likelihood of an event occurring in the future.
