Chapter 12 (TPT Unit) SG Companion

Front

What is the total number of outcomes when a spinner with 12 sections is spun twice and a card is drawn from a standard deck?

Back

The total number of outcomes is 12 (from the spinner) * 12 (from the spinner) * 52 (from the deck) = 7448.

Front

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

Back

Multiply the probability of the first event by the probability of the second event.

Front

What is the probability of drawing a boy from a class of 12 girls and 16 boys?

Back

The probability of drawing a boy is 16/(12+16) = 16/28 = 4/7.

Front

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

Back

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

Front

If Ryan pitched in 5/8 of the games and it rained in 3/10 of the games, how do you find the probability that it rained given that Ryan pitched?

Back

Use the formula P(Rain | Pitched) = P(Rain and Pitched) / P(Pitched).

Front

What does the intersection of two sets represent?

Back

The intersection of two sets A and B is the set of elements that are common to both A and B.

Front

How do you find the intersection of two sets?

Back

List all elements in both sets and identify the elements that appear in both.

Front

What is the probability of an event that cannot happen?

Back

The probability of an impossible event is 0.

Front

What is the probability of an event that is certain to happen?

Back

The probability of a certain event is 1.

Front

How do you calculate the probability of multiple independent events?

Back

Multiply the probabilities of each individual event.
