At Kennedy Middle School, the probability that a student takes Technology and Spanish is 0.087. The probability that a student takes Technology is 0.68. What is the probability that a student takes Spanish given that the student is taking Technology?

• we should use one formula here P(B/A)=P(A and B)/P(A).
  given P(A)=0.68 and P(A and B)=0.087,
  apply in above formula and you will be getting answer as
  P(B/A)=0.129 or 0.13 (i.e) answer
