Predicting Probabilities in Simple and Compound Events

What are the two types of events discussed in theoretical probabilities?

• Complex and Simple

• Simple and Compound

• Multiple and Single

• Dependent and Independent

What does theoretical probability aim to predict?

• Results of past events

• Historical data analysis

• None of the above

• Outcomes of future experiments

What is the probability of a coin landing on tails?

• 1/4

• 1/3

• 2/3

• 1/2

If a coin is flipped 50 times, how many times is it expected to land on tails?

• 25 times

• 20 times

• 30 times

• 50 times

How is the probability of a simple event like flipping a coin calculated?

• By guessing based on past results

• By multiplying the number of favorable outcomes by 100

• None of the above

• By dividing the number of favorable outcomes by the total outcomes

What is the probability of drawing a blue marble from a bag containing two blue marbles out of ten?

• 1/2

• 1/5

• 1/10

• 2/10

If 100 marbles are drawn, how many times would a blue marble be expected to be drawn?

• 10 times

• 15 times

• 25 times

• 20 times

What is the combined probability of flipping a coin and it landing on tails, then drawing a blue marble?

• 1/20

• 1/10

• 1/25

• 1/5

If the compound event of flipping a coin and drawing a blue marble is repeated 200 times, how many times is it expected to occur?

• 10 times

• 20 times

• 30 times

• 40 times

In the context of compound probability, what does 'top times top and bottom time bottom' refer to?

• Dividing fractions

• Adding fractions

• Subtracting fractions

• Multiplying fractions
