Basic Probability Concepts

What value does the probability range from?

In a fair coin toss, what is the probability of getting heads or tails?

For a standard die numbered from 1 to 6, what is the probability of rolling a 3?

What do results of trials become closer to as more trials are conducted?

How should the sum of probabilities for all possible outcomes of a trial total?

How is the probability of an event calculated?

What must be true about probability values?

Probability is a value that tells us how likely an event is to happen, ranging from 0 (impossible) to 1 (certain).
In a fair coin toss, the probability of getting heads or tails is 1/2, as each side is equally likely.
A standard die has 6 sides numbered 1 through 6, with each number having a probability of 1/6 when rolled.
Trials/experiments involve random outcomes like coin tosses or dice rolls, with results becoming closer to expected probabilities as more trials are conducted.
The sum of probabilities for all possible outcomes of a trial always equals 1 or 100%.
Probabilities can be represented as fractions, decimals, or percentages, making it easier to understand likelihood.
The probability of an event is calculated by the number of desired outcomes over the total number of possible outcomes.- Probability of pulling out a white marble is 1/11 or 0.09 or 9%, making it not very likely.
When adding up all probabilities, the total sum is 11/11 or 100%, as expected.
Basic probability involves creating a fraction with the desired outcomes as the numerator and the total possibilities as the denominator.
Probability values must fall between 0 and 1 (or 100%).
Conducting more trials or experiments brings results closer to the expected probabilities.
