Question

P (A) = 0.7, P (B) = 0.6, P( A u B) = 0.85 then P (A/B) =

Answer 1

Answer:

Answer=0.75

Step-by-step explanation:

p(A U B )= P(A)+P(B) - P(A intersect B)

0.85=0.7+0.6-P(A intersect B)

0.85=1.3-P(A intersect B)

P(A intersect B) =1.3-0.85

=0.45

P(A/B) =P(A intersect B) /P(B)

=0.45/0.6

=0.75
