(i) treated with the drug
(ii) not treated with the drug
(b) The probability that a fowl treated with the drug will die is 1/10
, while the probability that one which is not
treated will die is 7/10
Calculate the probability that a fowl picked at random from the sample is
(i) treated with the drug and will die
(ii) not treated with the drug and will die
(iii) treated with the drug and will not die
