The blood types of individuals in society are as follows: A: 30%, B: 25%, AB: 20%, 0: 25%. It is known that the rates of contracting a certain disease according to blood groups are as follows: A: 7%, B: 6%, AB: 7%, 0: 4%. Accordingly, if a person selected by chance is known to have this disease, what is the probability of having blood group O?

Exercise The temperature T in degrees Celsius of a chemical reaction is given as a function of time t, expressed in minutes, by the function defined on ΒΏ by: T (t )=(20 t +10)eβ0.5t. 1) What is the initial temperature? 2) Show that T' (t )=(β10 t +15)eβ0 .5t. 3) Study the sign of T' (t ), then draw up the table of variations of T . We do not ask for the limit of T in +β. 4) What is the maximum temperature reached by the reaction chemical. We will give an approximate value to within 10β2. 5) After how long does the temperature T go back down to its initial value? We will give an approximate value of this time in minutes and seconds.
