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

Option C is right answer

Step-by-step explanation:

Given that 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.

Probability that Nathan is allergic to pennicillin and the test predicts it

=Prob (Nathan is allergic)*P(test predicts it correct)

= 0.75(0.98)

=0.245

the median is   36 orr sum like dat
