PS Unit 3 Review

Front

What is the probability of selecting both pairs of socks as blue from a drawer containing 8 pairs of white, 6 pairs of black, and 4 pairs of blue?

Back

The probability is 12/306.

Front

What outcomes are in the event "both coins land on the same side" when flipping two coins?

Back

The outcomes are HH and TT.

Front

How do you calculate the probability of a student being female?

Back

The probability is calculated as the ratio of female students to total students, which is 2427/3537.

Front

How many five-digit numbers can be formed if the leading digit and the last digit cannot be zero?

Back

The total number of five-digit numbers is 81,000.

Front

What is the probability of a person being left-handed given they are a woman?

Back

The probability is 50/475.

Front

Define probability in the context of selecting items from a set.

Back

Probability is the measure of the likelihood that an event will occur, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a probability experiment.

Front

Explain the concept of independent events in probability.

Back

Independent events are two or more events where the occurrence of one event does not affect the occurrence of the other.

Front

What is the formula for calculating the probability of two independent events A and B occurring?

Back

P(A and B) = P(A) * P(B).

Front

Define a pair of events in probability.

Back

A pair of events consists of two events that can occur simultaneously or sequentially, often analyzed to determine their joint probability.
