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)
and B -- an event of "using Gun B". Find out: P(B|T)
Note that:
| P(A) | = | 9 |
| P(B) | 10 |
