3.1 and 3.2 Probability

What is the probability of selecting three universal donors (O negative) at random?

• 0.01%

• 0.03%

• 0.05%

• 0.10%

What is a 'Sample Space' in probability?

• The set of all possible outcomes of a random experiment.

• A collection of events that can occur in a probability experiment.

• The likelihood of a specific outcome occurring.

• The average of all possible outcomes in a probability experiment.

What is the term for the list of all possible results when throwing a six-sided die twice?

• Sample Space

• Outcome List

• Result Set

• Probability Chart

How do you find the probability of multiple events occurring in sequence?

• Add the probabilities of each individual event if they are independent.

• Multiply the probabilities of each individual event if they are independent.

• Subtract the probabilities of each individual event if they are independent.

• Divide the probabilities of each individual event if they are independent.

What is the probability that none of four randomly chosen people are universal donors (O negative)?

• 50%

• 60%

• 75%

• 90%

If Mrs. Hettinger's blood type is B negative, what is the probability that two randomly chosen people will both have B negative blood?

• 0.0001

• 0.0004

• 0.01

• 0.02

What is the probability of rolling a 3 on a six-sided die?

• 1/2

• 1/3

• 1/6

• 1/4

Explain the 'Fundamental Counting Principle'.

• If one event can occur in m ways and a second can occur independently in n ways, then the two events can occur in m × n ways.

• The total number of outcomes is the sum of the outcomes of each event.

• The probability of an event is the ratio of the number of favorable outcomes to the total number of outcomes.

• If two events cannot occur at the same time, the total number of outcomes is the product of the outcomes of each event.

If the probability of an event is 0.2, what is the probability of the event not occurring?

• 0.5

• 0.2

• 0.8

• 0.1

What is the formula for calculating the probability of independent events?

• P(A and B) = P(A) + P(B)

• P(A and B) = P(A) × P(B)

• P(A and B) = P(A) - P(B)

• P(A and B) = P(A) / P(B)
