Probability Concepts and Applications

The video tutorial covers the basics of probability, distinguishing between theoretical and experimental probability. It includes a class activity involving dice rolling to explore probability concepts, followed by an analysis of the class data. The tutorial also explores probability through coin flipping scenarios and uses library data to predict future outcomes.

What is the probability of getting heads when flipping a fair coin?

• 100%

• 75%

• 25%

• 50%

In a game where you win by rolling a 1 or 2 on a six-sided die, what is the probability of winning?

• 1/2

• 2/3

• 1/6

• 1/3

What is the main difference between theoretical and experimental probability?

• Theoretical is based on predictions, while experimental is based on actual experiments.

• Both are based on actual experiments.

• Theoretical is based on actual experiments, while experimental is based on predictions.

• Both are based on predictions.

If you roll a die 10 times and win 3 times, what is the experimental probability of winning?

• 0.3

• 0.7

• 0.5

• 0.33

As the number of trials increases, what happens to the experimental probability?

• It converges to theoretical probability.

• It remains constant.

• It diverges from theoretical probability.

• It becomes more random.

If a class conducted 90 dice rolls and 30 were wins, what was the experimental probability of winning?

• 0.5

• 0.3

• 0.2

• 0.4

What would be surprising about flipping a coin 100 times and getting heads every time?

• It is impossible.

• It is a common occurrence.

• It is expected.

• It is highly unlikely but possible.

If a librarian records that 4 out of 10 patrons check out fiction books, what is the probability of the next patron checking out a fiction book?

• 0.8

• 0.6

• 0.4

• 0.2

What is the probability of getting exactly 50 heads in 100 coin flips?

• It is unlikely.

• It is guaranteed.

• It is impossible.

• It is likely but not guaranteed.

How can the probability of an event be expressed if 4 out of 10 trials are successful?

• 4/5

• 3/5

• 2/5

• 1/2
