Q1)Given a collection of points P in the plane , a 1-set is a point in P that can be separated from the
rest by a line, .i.e the point lies on one side of the line while the others lie on the other side. The number
of 1-sets of P is denoted by n1(P). The minimum value of n1(P) over all configurations P of 5 points in
the plane in general position (.i.e no three points in P lie on a line) is

Q2)Paul the octopus who has been forecasting the outcome of FIFA world cup matches with
tremendous accuracy has now been invited to predict ICC world cup matches in 2011. We will assume
that the world cup contenders have been divided into 2 groups of 9 teams each. Each team in a group
plays the other teams in the group. The top two teams from each group enter the semi finals ( after
which the winner is decided by knockout).
However, Paul has a soft spot for India and when India plays any team, Paul always backs India.
Alas, his predictions on matches involving India are right only 2 out of 3 times. In order to qualify for
the semi finals, it is sufficient for India to win 7 of its group matches. What is the probability that India
will win the ICC world cup?
a) (2/3)^10
b) (2/3)^9 + 8/3 * (2/3)^9
c) 8/3 * (2/3)^9
d) (2/3)^10 + 8/3*(2/3)^9
Q3) A toy train produces at least 10 different tunes when it moves around a circular toy track of radius

the same type?
a) 1 in 16

Q5)Six friends decide to share a big cake. Since all of them like the cake, they begin quarreling who
gets to first cut and have a piece of the cake. One friend suggests that they have a blindfold friend
choose from well shuffled set of cards numbered one to six. You check and find that this method works
as it should simulating a fair throw of a die. You check by performing multiple simultaneous trials of
picking the cards blindfold and throwing a die. You note that the number shown by the method of
picking up a card and throwing a real world die, sums to a number between 2 and 12. Which total
would be likely to appear more often – 8,9 or 10?
a) 8
b) All are equally likely
c) 9
d) 10
