Specify what E and F are.

Answer 1

61.7 = P(E|F) = P(live births in all pregancies | all ages)

E represent live birth among all pregnacies and F represent the all ages people among all pregancies

-----

19.1 = P(E|F)=P(induced abortions in all pregancies| age25-29)

E represent the induced abortions among all pregancies  ad F represent total persons aged 25-29 among all pregancies

------------

64.8 = P(E|F), here E represent live birth among white race people and F represent the all ages people among pregancies of white race people.

15.6=P(E|F),here E represent the induced abortions among white race people ad F represent persons aged 25-29 among pregancies of white race people.

52.6=P(E|F) ,here E represent the live birth among other race people and F represent the all ages people among pregancies of other race people.

31.0=P(E|F),here E represent the induced abortions among other race people ad F represent persons aged 25-29 among pregancies of other race people.
