General Rules
Given an event, A, what equation gives you the probability that event A will NOT occur?
What is ....
P(Ac) = 1 - P(A)
or
P(Ac)+P(A)=1
TJ is a high school basketball player. He has a 70% free throw percentage. Assuming each throw is independent, what is the probability that he gets his first successful throw on his third free throw in a game?
What is ...
0.3*0.3*0.7= 0.063
Events that do not impact each other's probability/knowing whether even A occurs does not tell us anything about whether event B occurs.
What is...
independent
What is ...
P(rolling three 4s) = P(4)*P(4)*P(4) = P(4)^3
or (1/6)*(1/6)*(1/6)= (1/6)^3
What college did Ms Coleman go to?
What is ...
Miami University
or
Cleveland State University
Given two independent events, A and B, what is the probability that event A and B occurs.
What is...
P(A ∩ B) = P(A) * P(B)
Sky has a 95% chance of getting an A on the test. If Sky gets an A, Jerred has a 90% chance of also getting an A. What is the probability they both get As?
What is...
P(Jerred and Sky)=P(Sky)* P(Jerred|Sky)
=0.95*0.9
=0.855
contains all of the possible outcomes
what is...
sample space
The rule for the probability of having a brother or a sister
What is...
P(bro or sis)= P(bro)+P(sis) - P(bro and sis)
What year was RHS Summit built?
What is ...
2011
Given two events, A and B, what is the probability that event A and B occurs.
What is...
P(A ∩ B) = P(A) * P(B|A)
Bath and Body Works offers a coupon to 50% of its online visitors, selected at random, each day. Ms. Coleman visits the website for 4 days.
What is the probability that Ms. Coleman will be offered a coupon on at least one of the days she visits the website?
What is...
1-P(no coupon offered)
1-(0.5)4
P(at least 1)=0.9375
two events that cannot occur simultaneously
What is....
mutually exclusive or disjoint
The rule for finding the probability of a female given that they are an AP stats student.
What is ... P(Female| AP Stats Student)= P(Female AP Stats student)/P(AP Stats student)
What is Ms. Coleman's daughter's name?
What is ...
Robin
or
Wren
Given two events, A and B, what is the probability that event A or event B occurs?
What is ...
P(A U B)= P(A) + P(B) - P(A ∩ B)
or
P(A U B)= P(A) + P(B) - P(A)*P(B|A)
Ms. Coleman is playing Papers Please, where you detect false documents at a border crossing. She can correctly tell 90% of the time if a document is falsified, and she never denies entry if she can't tell or if it's real. If 5% of the border crossers have false documents, what percent of border crossers will she prevent from entry?
What is ...
0.05*0.9=0.045
two events that cannot occur together, but one must happen
What is...
complementary
The probability of not drawing a pink or orange Starburst from a bag of Starburst
What is ...
1- P(pink starburst) - P(orange starburst)
or
1-P(pink or orange starburst)
What was an extracurricular Ms. Coleman did in high school?
What is....
marching band, track, tennis, quiz bowl, NHS, or cheerleading
Given a string of n trials in a probability experiment with a constant probability of success, what is the simplest way to calculate the probability of at least one success?
What is ...
P(at least one)= 1-P(none)
or
P(at least one)= 1-P(successc)n
A coin is tossed 3 times. What is the probability that it lands on heads exactly one time?
What is...
3/8 or 0.375
The three equations used to determine independence between 2 events.
What is...
P(A|B)=P(A)
or
P(B|A)=P(B)
or
P(A∩B)=P(A)P(B)
The probability that two people do not have the same birth month in a group of three people
12/12*11/12*10/12
or
11/12*10/12
