Question

If p(A intersection B)=0.3,p(A Bar intersection B)=0.45,then p(B)=​

Answer 1

Answer:

0.75

Step-by-step explanation:

P(A intersection B)=0.3

P(A bar intersection B)=0.45

P(A bar)= anything other than A

P(A intersection B)=common part of A and B

P(A bar intersection B)=any part which is common in B and parts other than A

                                     =B-A

P(B)=P(A bar intersection B)+P(A intersection B)

      =0.45+0.3

      =0.75
