What is Experimental Probability?

Back

Experimental Probability is what actually happens in an experiment, calculated as the ratio of the number of times an event occurs to the total number of trials.

Front

What is Theoretical Probability?

Back

Theoretical Probability is the ratio of favorable outcomes to the total number of possible outcomes.

Front

What is the probability of rolling a 1 or 6 on a die?

Back

1/3 (since there are 2 favorable outcomes out of 6 possible outcomes).

Front

What is the probability of spinning yellow if there are 12 equal sections?

Back

1/12 (since there is 1 favorable outcome out of 12 possible outcomes).

Front

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

Back

Impossible (the maximum total with two dice is 12).

Front

How do you calculate Experimental Probability?

Back

Experimental Probability = (Number of times the event occurs) / (Total number of trials).

Front

What does it mean if an event is 'impossible'?

Back

An event is impossible if it cannot happen, such as rolling a total of 15 with two dice.

Front

What does it mean if an event is 'likely'?

Back

An event is likely if it has a high chance of occurring, more favorable outcomes than unfavorable.

Front

What does it mean if an event is 'unlikely'?

Back

An event is unlikely if it has a low chance of occurring, more unfavorable outcomes than favorable.

Front

What is a favorable outcome?

Back

A favorable outcome is a result that satisfies the condition of the event we are interested in.
