Probability

A computer producing factory has only two plants T1 and T2 Plant T1 produces 20% and plant T2produces 80% of the total computers produced. 7% of computers produced in the factory turn outto be defective. It is known that
P(computer turns out to be defective given that is produced in plantT1
= 10P(computer turns out to be defective given that it is produced in plant T2
where P(E) denotes the probability of an event E. A computer produces in the factory is randomlyselected and it does not turn out to be defective. Then the probabality that it is produced in plant T2 is
