Compound Events

What is the difference between independent and dependent events?

• Independent events are those that do not affect each other's outcomes, while dependent events are those that do.

• Independent events are always more likely to occur than dependent events.

• Dependent events can occur simultaneously, while independent events cannot.

• Independent events are influenced by external factors, while dependent events are not.

What is the probability of getting at least one head when flipping two coins?

• 1/2

• 1/3

• 3/4

• 2/3

What is the significance of the total number of outcomes in probability?

• It is used to determine the likelihood of an event occurring.

• It helps in calculating the mean of a data set.

• It indicates the maximum possible score in a game.

• It shows the relationship between two variables.

What is a compound event in probability?

• A compound event is an event that consists of two or more simple events. For example, flipping two coins is a compound event.

• A compound event is an event that can only occur once in a given experiment.

• A compound event is an event that has no possible outcomes.

• A compound event is an event that consists of only one simple event.

What is the probability of selecting a prime number and then a 4 from a set of cards?

• 1/10

• 1/5

• 3/20

• 1/4

What is the probability of getting all heads when flipping four coins?

• 1/8

• 1/16

• 1/4

• 1/2

How do you find the total number of outcomes when rolling two dice?

• Add the number of outcomes for the first die to the number of outcomes for the second die (6 + 6 = 12).

• Multiply the number of outcomes for the first die by the number of outcomes for the second die (6 x 6 = 36).

• Subtract the number of outcomes for the first die from the number of outcomes for the second die (6 - 6 = 0).

• Divide the number of outcomes for the first die by the number of outcomes for the second die (6 / 6 = 1).

What is a simple event in probability?

• An event that consists of multiple outcomes.

• An event that consists of a single outcome, such as rolling a 3 on a die.

• An event that cannot occur under any circumstances.

• An event that has an equal chance of occurring as not occurring.

What is the probability of selecting the same toy from a treasure chest with replacement?

• 1/125

• 1/625 for selecting the same toy twice.

• 1/250

• 1/500

What is the formula for calculating the probability of an event?

• Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

• Probability = (Total number of possible outcomes) / (Number of favorable outcomes).

• Probability = (Number of unfavorable outcomes) / (Total number of possible outcomes).

• Probability = (Number of favorable outcomes) + (Total number of possible outcomes).
