Test your knowledge on conditional probability, Bayes' theorem, and probability chains with this comprehensive quiz!
#1
What is conditional probability?
The probability of an event occurring given that another event has already occurred
The probability of two independent events occurring simultaneously
The probability of an event occurring in isolation
The probability of an event not occurring
#2
In probability, what does P(A and B) represent?
The conditional probability of A given B
The union of events A and B
The intersection of events A and B
The complement of event A
#3
What is the formula for conditional probability P(A | B)?
P(A and B) / P(B)
P(A) / P(B)
P(A) * P(B)
P(B | A) / P(A)
#4
If events A and B are independent, what is P(A and B)?
P(A) * P(B)
P(A) + P(B)
P(A) / P(B)
P(A) - P(B)
#5
If events A and B are mutually exclusive, what is P(A and B)?
P(A) * P(B)
P(A) + P(B)
P(A) / P(B)
0
#6
What is the complement of an event in probability?
The intersection of events
The union of events
The probability of the event not occurring
The conditional probability
#7
What is a probability chain in probability theory?
A sequence of independent events
A sequence of dependent events
A sequence of mutually exclusive events
A sequence of impossible events
#8
In a deck of playing cards, what is the probability of drawing two consecutive cards of the same suit without replacement?
#9
What is the Law of Total Probability?
P(A | B) = P(B | A) * P(A) / P(B)
P(A) = P(A | B) * P(B) + P(A | B') * P(B')
P(A and B) = P(A) * P(B | A)
P(A or B) = P(A) + P(B) - P(A and B)
#10

Calculating conditional probability
Finding the union of two events
Determining independent events
Solving combinatorial problems
