We have three different drugs T, F and H. Drugs T and F cure a V virus in 60% and 80% of cases, respectively, and the drug Hes introduced by mistake in the prescription and if it is administered to patients with the V virus produces serious secondary effects in them without curing the virus. Assume that the effects of the 3 drugs are independent. The treatment consists: first, one of the drugs is randomly administered. After a defined time, if it is not cured, one of the remaining drugs is randomly administered, if it is not cured either, then the third drug is administered. In addition, given the serious side effects caused by H, the treatment is interrupted, that is, no other prescription is administered. What is the probability that he will be cured of the virus knowing that he was given drug F rst (1 st administration)?
