instructions: (There are 20 questions to be answered for Module 7)
The following 6 questions (Q1 to Q6) are based on the following summarized data below:
Given the upcoming NBA draft, there are 100 players available:
College Experience (CE) No College Experience (NCE)
Point Guard (PG) 14 2

Power Forward (PF) 15 6
Find the following probabilities:
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 3 black labs, 5 yellow
labs, and 2 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:

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

The following 5 questions (Q16 to Q20) are either “True” or “False”
Q16: The ‘Subjective View’ uses an analysis of possible outcomes to define probability
Q17: ‘Mutually Exclusive Events’ is when the occurrence of one event has no effect on the
probability of occurrence of the other.
Q18: ‘Gambler’s Fallacy’ is the incorrect belief that the probability of a particular event
changes after a series of the event has taken place.
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.
Q20: Flipping a coin repeatedly is a series of “Independent Events
