Three bags contain balls as shown in the table below:


A bag is chosen at random and two balls are drawn from it. They happen to be white and red. What is the probability that they came from the III bag?


The probability of choosing bag


P(Bag I) = P(Bag II) = P(Bag III)


Also,


Let E be the event the balls chose happens to be white and red


P(E/Bag I)


P(E/Bag II)


P(E/Bag III)


We have to find the probability that the balls came from the III bag i.e. P(Bag III/E)


And we know,


P(Bag III/E) =

A diet is to contain at least 80 units of Vitamin A and 100 units of minerals. Two foods F1 andF2 are available. Food F1 costs Rs. 4 per unit and F2 costs Rs. 6 per unit. One unit of food F1contains 3 units of Vitamin A and 4 units of minerals. One unit of food F2 contains 6 units ofVitamin A and 3 units of minerals. Formulate this as a linear programming problem and findgraphically the minimum cost for diet that consists of mixture of these two foods and alsomeets the minimal nutritional requirements.
