Probability of Independent Events
3 Activities
Event A and Event B are mutually exclusive. Which of the following is true?
P
(
A
∩
B
)
=
P
(
A
)
+
P
(
B
)
P\left(A\cap B\right)=P\left(A\right)+P\left(B\right)
P
(
A
∩
B
)
=
P
(
A
)
+
P
(
B
)
If
P
(
A
)
=
1
P\left(A\right)=1
P
(
A
)
=
1
, then
P
(
B
)
=
0
P\left(B\right)=0
P
(
B
)
=
0
Event A and Event B must be indepdendent.

Trish and Stevie are in a newlywed game show where they have to answer questions about each other. There are 3 rounds so each will be asked 3 questions. The probability that Trish answers a question about Stevie correctly is 76%. The probability that Stevie answers a question about Trish correctly is 45%. They are asked different questions so the answers one provides have no impact on the answers the other provides.
In Round 1, they are each asked one question. What is the probability that at least one of them answers correctly?
