Question

P(A) = 0.39 P(B) = 0.41 P(A ∪ B) = 0.63 Find P(A ∩ B).

Answer 1

Step-by-step explanation:

P(A ∩ B)= P(A)×P(B)

= 0.39×0.41

P(A ∩ B) =0.1599

Answer 2

given:

P(A) is the probability of an event “A”

P(A) = 0.39

P(B) = 0.41

P(A∪B) = 0.63

we know that

the rule of addition P(A∪B) = P(A)+ P(B)-P(A∩B)

  then                        P(A∩B)= P(A)+ P(B)- P(A∪B)

                                              =0.39+0.41-0.63

answer                     P(A∩B)=0.17
