robbery

[logistic_guy]

If $\displaystyle R$ is the event that a convict committed armed robbery and $\displaystyle D$ is the event that the convict pushed dope, state in words what probabilities are expressed by

$\displaystyle \bold{(a)} \ P(R|D)$
$\displaystyle \bold{(b)} \ P(D'|R)$
$\displaystyle \bold{(c)} \ P(R'|D')$

$\displaystyle \bold{(a)}$

Let us assume that the convict is a girl.

$\displaystyle P(R|D)$ is the probability that a convict committed armed robbery given that she pushed dope.
