If AA and BB are two disjoint events with P(A)=0.15P(A)=0.15 and P(B)=0.75P(B)=0.75, find the following probabilities:

zubka84 [21]

Answer:

a 0

b) 0.9

c) 0.85

d) 0.25

e) 0.1

f) 0.0375

Step-by-step explanation:

As A and B are two disjoints events, then P(A and B) is

P(A and B)=0

As A and B are two disjoints events, then P(A or B) is

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

P(A or B)=0.15+0.75=0.9

P(not A)=1-P(A)

P(not A)=1-0.15=0.85

P(not B)=1-P(B)

P(not B)=1-0.75=0.25

P(not (A or B))=1-P(A or B)

P(not (A or B))=1-0.9=0.1

P(A and (not B))=P(A)*P(not B)

P(A and (not B))=0.15*0.25=0.0375
