Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan's father and paternal grandfather were all
ergic to
penicillin, Nathan had a 75% chance of having the same allergy. The doctor performed a skin test to see whether Nathan would react to it. The
test is 98% accurate. What is the probability that Nathan is allergic to penicillin and the test predicts it?
A. 0.005
B. 0.015
C. 0.245
D.
0.735

Euclid used a somewhat different parallel postulate in trying to avoid the notion of the infinite. He observed that when two parallel lines are intersected by a third line, called a transversal, then if you measure two angles formed by these three lines, on the same side of the transversal and between the parallels, they will add to (that is, they will be supplementary). Such angles are called same-side interior angles<span>:</span>
