Question

Consider two events with P(A)=.4, P(B|A)=.5 and P(A or B)=.7

a) find P(A and B)=

b) find P(B)=

c) Are A and B independent? Explain

d) Find P(A|B)

Expert Solution
Step 1

The provided information are:

                                                   P(A)=0.4P(B|A)=0.5P(A or B)=0.7

by using the following formulas calculate the given probability :

                                                                      P(B|A)=P(A and B)P(A)andP(Aor B)=P(A)+P(B)-P(A and B)
