What is experimental probability?

Back

Experimental probability is the probability determined by conducting an experiment and recording the outcomes.

Front

How do you calculate experimental probability?

Back

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

What is the probability of rolling a 4 on a six-sided die?

Back

1/6, since there is one favorable outcome (rolling a 4) out of six possible outcomes.

Front

What is the total number of outcomes when rolling a die?

Back

6, because a standard die has six faces numbered from 1 to 6.

Front

What is the probability of flipping a coin and getting heads?

Back

1/2, since there are two possible outcomes (heads or tails).

Front

What is the probability of rolling a six-sided die and getting a 6?

Back

1/6, as there is one favorable outcome out of six possible outcomes.

Front

What is the probability of two independent events occurring?

Back

The probability of two independent events occurring is the product of their individual probabilities.

Front

What is the probability of flipping a coin and rolling a die?

Back

1/2 (for heads) * 1/6 (for rolling a 6) = 1/12.

Front

What does it mean for events to be independent?

Back

Independent events are those whose outcomes do not affect each other.
