A shopkeeper sells three types of seeds `A_1, A_2a n dA_3` They are sold as a mixture where the proportions are 4:4:2 respectively. The germination rate of three types of seeds are 45%, 60% and 35%. Calculate the probability (i)that it will germinate given that the seed is of type `A_3` . (ii)of a randomly chosen seed to germinate. (iii)That it is of type `A_2` given that a randomly chosen seed does not germinate.
