Question

If P(A) = \(\frac{6}{11},\) P(B) = \(\frac{5}{11}\) and P(A ∪ B) = \(\frac{7}{11},\) then P(A/B)=?

A. \(\frac{5}{6}\)

B. \(\frac{5}{7}\)

C. \(\frac{6}{7}\)

D. \(\frac{4}{5}\)

Answer 1

Correct answer is D.

P(A) = \(\frac{6}{11},\) P(B) = \(\frac{5}{11}\) and P(A ∪ B) = \(\frac{7}{11}\)
