Q1: p(PF)

Q2: p(C and NCE)

Q3: p(CE)

Q4: p(SF/CE)

Q5: p(not SG)

Q6: p(CE/PF)

The following 3 questions (Q7 to Q9) are based on the following information:

You have a kennel that contains all Labrador Retrievers. The kennel has 10 black labs, 6 yellow labs, and 4 chocolate labs.

Find the following probabilities:

Q7: What's the probability that you randomly select a black lab, don't put the lab back, then draw another black lab, don't put the lab back, and then draw another black lab?

Q8: What's the probability that you draw a yellow or chocolate lab on the first draw, replace the dog, and then draw a black lab?

Q9: What's the probability that you draw a yellow lab on the first draw, don't put the lab back, and then draw either a yellow or chocolate lab on the second draw?

The following 3 questions (Q10 to Q12) are based on the following information:

John has the phone numbers of many young ladies. Some of these young ladies are blonde and others are brunettes. In addition, John knows that some are single while others have boyfriends. The exact breakdown is as follows:

Blonde Brunette

Single 15 12

Taken 10 18

Find the following probabilities:

Q10: What is the probability of selecting someone who is taken, given that they are blonde?

Q11: What is the probability of selecting a single brunette?

Q12: What is the probability of selecting someone who is brunette, given that they are taken?

Q13: A coin is tossed four times. Which of the following sequences of heads (H) and tails(T) is more likely?

C. 0.00 to +1.00

D. -1.00 to +1.00

The following 5 questions (Q16 to Q20) are either "True" or "False"

Q16: 'Gambler's Fallacy' is the incorrect belief that the probability of a particular event changes after a series of the event has taken place.

Q17: 'Mutually Exclusive Events' is when the occurrence of one event has no effect on the probability of occurrence of the other.

Q18: The 'Subjective View' uses an analysis of possible outcomes to define probability

Q19: The probability of randomly guessing at the first three multiple choice questions on an exam, each of which has four possible

answers, is 0.015625. Q

20: Flipping a coin repeatedly is a series of "Independent Events"
