Probability Quiz

What is the difference between dependable and independent probability?

• Dependable probability is when events are independent, while independent probability is when events are dependent.

• Dependable probability is when events are not independent, while independent probability is when events are independent.

• Dependable probability is when events are independent, while independent probability is when events are not independent.

• Dependable probability is when events are dependent, while independent probability is when events are not dependent.

If two events are independent, what is the probability of both events occurring?

• P(A) + P(B)

• P(A) - P(B)

• P(A) / P(B)

• P(A) * P(B)

If two events are dependent, how is the probability of both events occurring calculated?

• Subtract the probability of the first event from the probability of the second event

• Divide the probability of the first event by the probability of the second event

• Add the probabilities of both events

• Multiply the probability of the first event by the conditional probability of the second event given the first event has occurred.

What is the formula for calculating the probability of A and B if A and B are independent events?

• P(A and B) = P(A) - P(B)

• P(A and B) = P(A) + P(B)

• P(A and B) = P(A) * P(B)

• P(A and B) = P(A) / P(B)

In a deck of cards, what is the probability of drawing a red card and then drawing a black card if the cards are not replaced?

• 1/4

• 1/3

• 1/2

• 1/5

Explain the concept of conditional probability.

• Conditional probability is the likelihood of an event occurring given that another event has already occurred.

• Conditional probability is the likelihood of an event occurring before another event takes place.

• Conditional probability is the likelihood of an event occurring independently of any other event.

• Conditional probability is the likelihood of an event occurring without any relation to other events.

What is the formula for calculating the probability of A and B if A and B are dependent events?

• P(A and B) = P(A) * P(B|A)

• P(A and B) = P(A) / P(B)

• P(A and B) = P(A) + P(B)

• P(A and B) = P(A) - P(B)

In a bag of marbles, there are 4 red, 3 blue, and 5 green marbles. What is the probability of drawing a red marble followed by a blue marble without replacement?

• 3/10

• 1/11

• 2/11

• 1/12

How can you determine if two events are independent or dependent based on their probabilities?

• Calculate the joint probability of both events occurring and compare it to the product of the individual probabilities.

• Check if the events have similar starting letters

• Ask a friend for their opinion

• Flip a coin to decide if they are independent or dependent
