Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were allergic 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? 0.005 0.015 0.245 0.735

    the 2 probabilities mentioned here are with regard to the allergy and the accuracy of the test . These are independent of each other so in combination they are multiplied.
