Two guns are used in a battle. Gun A, having accuracy of 0.8, spits 9 bullets per minute. Gun B, having accuracy of 0.7, spits 10 bullets per minute. A target was hit! What is the probability that the target was hit by Gun B. Let T be an event of "hitting the target" and B -- an event of "using Gun B". Find out: P(B|T)

Note that: P(A) = 9 P(B) 10
