Simple Probability & Likelihood

Front

What is the sample space for tossing one coin?

Back

The sample space consists of 2 outcomes: Heads (H) and Tails (T).

What is the probability of drawing a lemon from a bag containing 30 pieces of candy (15 grape, 7 cherry, 3 lemon, 5 strawberry)?

Back

The probability of drawing a lemon is 1/10.

Front

What does it mean if the experimental probability and theoretical probability are equal?

Back

It means that the outcomes observed in an experiment match the expected outcomes based on theoretical calculations.

Front

How can probability be expressed?

Back

Probability can be expressed as a fraction, a percent, or a decimal.

Front

If you select a marble without looking, how likely is it that you will pick a black OR green one if there are black and green marbles in the selection?

Back

It is certain that you will pick a black or green marble.

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 an example of an event with a probability of 0?

Back

An event that is impossible, such as rolling a 7 on a standard 6-sided die.

Front

What is an example of an event with a probability of 1?

Back

An event that is certain, such as the sun rising tomorrow.

Front

What is the formula for calculating probability?

Back

Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

What is the difference between experimental probability and theoretical probability?

Back

Experimental probability is based on actual experiments, while theoretical probability is based on expected outcomes.
