Two dice, one blue and one grey are thrown at the same time. Write down all the possible outcomes. : A student argues that 'there are 11 possible outcomes 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12. Therefore, each of them has a probability `1/11`. Do you agree with his argument ? Justify you answer :

Which of the following arguments are correct ? Give reasons for your answer : If two coins are tossed simultaneously there are three possible outcomes - two heads, two tails or one of each. Therefore, for each of these outcomes, the probability is 1/3 .

A game of chance consists of spinning an arrow which comes to rest pointing at one of the numbers 1, 2, 3, 4, 5, 6, 7, 8 and these are equally likely outcomes. What is the probability that it will point at : a number greater than 2 ?

A manufacturer considers that men and women are equally efficient and so he pays them at the same rate. He has 30 and 27 units of workers ( male and female) and capital respectively, which he uses to produce two types of goods A and B. To produce one unit of A 2 workers and 3 units of capital are required while 3 workers and 1 unit of capital are required to produce one unit of B. If A and B are priced at Rs 100 and Rs 120 per unit respectively, how should he use his resources to maximise the total revenue? From the above as as LPP and solve graphically. Do you agree with this view of the manufacturer that men and women are equally efficient and so should be paid at the same rate?
