A sample space consists of 9 elementary event E1,E2,E3.....E8,E9
whose probabilities are P(E1)=P(E2)=0.08
,P(E3)=P(E4)=0.1
, P(E6)=P(E7)=0.2
,P(E8)=P(E9)=0.07
. Suppose A={E1,E5,E8}
, B={E2,E5,E8,E9}
. Compute P(A)
, P(B)
and P(A∩B)
. Using the addition law of probability, find P(A∪B)
. List the composition of the event A∪B
, and calculate, P(A∪B)
by adding the probabilities of the elementary events. Calculate P(
ˉ
B
)
from P(B)
, also calculate P(
ˉ
B
)
directly from the elementary events of
ˉ
B
.
