Experimental Probability of Simple Events

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials conducted.

Front

How is experimental probability calculated?

Back

Experimental probability is calculated using the formula: P(event) = (Number of times the event occurs) / (Total number of trials).

Front

What is a simple event in probability?

Back

A simple event is an event that consists of a single outcome.

Front

How many outcomes are there in a simple event?

Back

There is only one outcome in a simple event.

Front

If a spinner has 4 equal sections and lands on Red 3 times out of 20 spins, what is the experimental probability of landing on Red?

Back

P(Red) = 3/20.

Front

What is the experimental probability of an event that occurs 12 times out of 50 trials?

Back

P(event) = 12/50 or 6/25.

Front

If a die is rolled 5 times and the result is 3, 1, 4, 3, 4, what is the experimental probability of rolling a 3?

Back

P(3) = 2/5.

Front

What is the total number of trials if a spinner lands on Red 60 times?

Back

The total number of trials is the sum of all outcomes, which must be provided to calculate the probability.

Front

What is the experimental probability for BLUE if it occurs 10 times out of 50 trials?

Back

P(BLUE) = 10/50 or 1/5.

Front

What does it mean if the experimental probability of an event is close to its theoretical probability?

Back

It indicates that the experimental results are consistent with the expected outcomes based on probability theory.
