Exploring Independent and Dependent Probability

What defines an independent event in probability?

• An event that always results in the same outcome.

• An event that is influenced by the outcome of another event.

• An event where the outcome is not affected by other events.

• An event that cannot occur simultaneously with another event.

How do you calculate the probability of two independent events occurring?

• Multiply the probability of one event by the probability of the other.

• Subtract the probability of one event from the probability of the other.

• Divide the probability of one event by the probability of the other.

What is the probability of selecting a vowel and then landing on blue in a game involving letter tiles and a spinner?

• 1/8

• 1/4

• 1/6

• 1/12

What changes in the probability calculation for dependent events compared to independent events?

• There is no change in how probabilities are calculated.

• The probabilities are added instead of multiplied.

• The second event's probability is adjusted based on the outcome of the first.

• The probabilities are divided instead of multiplied.

How does removing a piece of fruit from a basket after selecting it affect subsequent selections?

• It makes subsequent selections independent.

• It does not affect the probability of subsequent selections.

• It increases the probability of selecting the same type of fruit.

• It makes subsequent selections dependent.
