General Rules
Given an event, A, what equation gives you the probability that event A will NOT occur?
What is ....
P(A') = 1 - P(A)
or
P(A')+P(A)=1
A coin is tossed 3 times. What is the probability that it lands on heads exactly one time?
What is...
0.375
Events that do not impact each other's probability.
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 colleges did Mr. Jackson go to?
What is ...
Fisk University and Vanderbilt University
Given two independent events, A and B, what is the probability that event A and B occurs.
What is...
P(A and B) = P(A) * P(B)
Armando is a high school baseball player. He gets a hit 70% of the time. That means his average is 0.70. What is the probability that he gets his first successful hit on his third swing?
What is ...
0.3*0.3*0.7= 0.063
two events that cannot occur simultaneously
What is....
mutually exclusive or disjoint
The rule for the probability of pulling a red or queen from a standard deck of cards.
What is...
P(Red or Queen)= P(red)+P(queen) - P(red and queen)
The grade and subject did Mr. Jackson teach first
What is ...
10th grade Geometry
Given two mutually exclusive events, A and B, what is the probability that event A or event B occurs?
What is ...
P(A or B)= P(A) + P(B)
The two equations used to determine independence between 2 events.
What is...
P(A|B)=P(A)
or
P(B|A)=P(B)
two events that cannot occur together, but one must happen
What is...
complementary
The rule for finding the probability of a female given that they are an AP stats student.

What is....
Major in Mathematics
2nd Major in Business
Given two events, A and B, what is the probability that event A and B occurs.
What is...
P(A and B) = P(A) * P(B|A)
90% of the people who have a particular disease will have a positive result on a given diagnostic test (90% accuracy). If 5% of a certain population has the disease, what percent of that population would test positive for the disease?
What is ...
14% or 0.14
events that do not impact each other's probability
what is ...
dependent
The probability of not drawing a red ace or a club from a standard deck of card
What is ...
1- P(drawing a red ace) - P(drawing a club)two physical activities that Mr. Jackson participates in
What is ...
Yoga
Mixed Martial Arts
Practicing Nunchaku
Hiking
Given two events, A and B, what is the probability that event A or event B occurs?
What is ...
P(A or B)= P(A) + P(B) - P(A and B)
or
P(A or B)= P(A) + P(B) - P(A)*P(B|A)
Two events are this if they share no outcomes in common
What is ...
disjoint or mutually exclusive
contains all of the possible outcomes
what is...
sample space
The rule for finding the probability of 2 or more people from a group of 5 having the same birthday
1- P(none have the same birthday)
P(none have the same birthday)= (365/365) *(364/365) * (363/365) * (362/365) * (361/365)
