What is experimental probability?

Back

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

Front

How do you calculate experimental probability?

Back

Experimental probability is calculated using the formula: \( P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total number of trials}} \)

What is a compound event in probability?

Back

A compound event is an event that consists of two or more simple events. For example, rolling a die and flipping a coin.

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on the expected outcomes in a perfect world, while experimental probability is based on actual experiments and observations.

If a dentist has 400 patients and 50 are females aged 22-39, what is the experimental probability that the next patient is a female in that age range?

Back

The experimental probability is \( P = \frac{50}{400} = \frac{1}{8} \)

In a vehicle classification problem, if 3 out of 25 vehicles are cars that turn right, what is the experimental probability?

Back

The experimental probability is \( P = \frac{3}{25} \)

What is the experimental probability of selecting a specific order from a food trailer if there are 18 total orders and 3 are for 3-pieces with cole slaw?

Back

The experimental probability is \( P = \frac{3}{18} = \frac{1}{6} \)

How do you find the experimental probability of a drink being a small cocoa if 3 out of 20 drinks sold were small cocoa?

Back

The experimental probability is \( P = \frac{3}{20} \)

If there are 50 vehicles in a parking lot and 7 are red cars, what is the experimental probability of selecting a red car?

Back

The experimental probability is \( P = \frac{7}{50} \)

Front

What is the formula for calculating the probability of independent events?

Back

For independent events, the probability of both events occurring is \( P(A \text{ and } B) = P(A) \times P(B) \)
