What does 'or' signify in probability calculations?

• Multiplication of probabilities

• Addition of probabilities

• Subtraction of probabilities

• Division of probabilities

In the context of probability, what does the term 'exclusive' imply?

• The events are dependent

• The events cannot occur simultaneously

• The events are independent

• The events can occur simultaneously

What operation is used to combine probabilities of independent events?

• Division

• Multiplication

• Subtraction

• Addition

What is the significance of the 'and' operation in probability?

• It signifies addition of probabilities

• It signifies subtraction of probabilities

• It signifies multiplication of probabilities

• It signifies division of probabilities

In the example with marbles, what is the probability of drawing a blue marble first and then a red marble, if the blue marble is replaced?

• 5.2%

• 16.5%

• 33%

• 2.8%

What does replacing a marble in the bag signify in terms of event dependency?

• The probability increases

• The events are dependent

• The probability decreases

• The events are independent

What term describes the probability affected by previous outcomes?

• Exclusive probability

• Conditional probability

• Dependent probability

• Independent probability

What is the effect of not replacing a marble on the probability of the next draw?

• Increases the total number of marbles

• Does not affect the total number of marbles

• Decreases the total number of marbles

• Makes the events exclusive

What is the probability of drawing a blue and then a green marble without replacing the blue marble?

How does the probability of subsequent events change when the first event's outcome is not replaced?

• It becomes zero

• It remains the same

• It increases

• It decreases
