Unit 5 Test - AP Stats Probability

Front

What is the probability of drawing a 10 from a standard deck of 52 cards?

Back

The probability is \( \frac{4}{52} \) because there are 4 tens in a deck.

Front

What does it mean when two events are dependent?

Back

Dependent events are those where the outcome of one event affects the outcome of another.

Front

How do you calculate the probability of either event A or event B occurring?

Back

Use the formula: \( P(A \text{ or } B) = P(A) + P(B) - P(A \text{ and } B) \)

Front

What is the probability of not choosing a red rose from a vase containing 12 red, 5 yellow, and 3 white roses?

Back

The probability is \( \frac{8}{20} \) because there are 8 non-red roses out of 20 total.

Front

If the probability of getting tails on a biased coin is 0.4, what is the probability of getting heads?

Back

The probability of getting heads is 0.6, calculated as \( 1 - 0.4 \).

Front

Define independent events in probability.

Back

Independent events are those where the outcome of one event does not affect the outcome of another.

Front

What is the total number of outcomes when rolling a six-sided die?

Back

There are 6 possible outcomes: 1, 2, 3, 4, 5, or 6.

Front

How do you find the probability of an event?

Back

The probability of an event is found using the formula: \( P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \)

Front

What is the probability of drawing a heart from a standard deck of cards?

Back

The probability is \( \frac{13}{52} \) because there are 13 hearts in a deck.

Front

Explain the concept of mutually exclusive events.

Back

Mutually exclusive events cannot occur at the same time; the occurrence of one event excludes the possibility of the other.
