Question

Events A and B are mutually exclusive.
Also, P(A) = 0.15 and P(B) = 0.2.

What is P(A or B)?

A.
0.35

B.
0.03

C.
0.05

D.
0.20

Answer 1

P(A or B) = P(A) + P(B)
(for mutually exclusive events)

Answer 2

i'm lost O.o

Answer 3

the probability of event \(P(A or B)\) is the same thing as the probability of \(A\) happening and \(B\) happening.

so \(P(A or B)=P(A)+P(B)\)

Answer 4

in our case:
P(A) = 0.15 and P(B) = 0.2.

P(A or B)=P(A)+P(B)

Answer 5

so a ?
