Question

While taking a quiz, you guess on 3

questions in a row. What is the
probability you guessed all three
correctly?

Answer 1

P(A): 1

P(A'): 0

P(B):

1

P(B' ):

0

P(A ∩ B): 1

P(A ∪ B): 1

P(A | B): 1

Explanation:

To find the probability, divide the possible number of events to happen by total number of events. While the impossibility of the event can be found by subtracting the possible probability by one. Probability of event A that occurs P(A) = n(A) / n(S). Probability of event A that does not occur P(A) = 1 - P(A).
