- Following data is about the CGPA of two classes. Class A: 1.90, 2.01, 3.21. 3.12, 4.00, 2.99, 3.78, 4.00, 3.56, 2.11, 1.55, 2.76, 3.44, 3.56, 1.99, Class B: 1.59, 4.00, 2.45, 3.98, 1.99, 2.99, 2.56, 3.33, 2.67, 2.55, 3.67, 3.89, 3.03, 3.01, 3.58. Which class performance is most consistent? Explain with the help of the most appropriate method of relative measure of dispersion. b- The p.d. of a discrete random variable X is: f(x)=(?(7@x))?(1/4)?^(x ) ?(3/4)?^(5-x), x=0, 1,2,3,4,5, 6, 7 Make a probability distribution and compute the E(X) and Var(X). c- Two team A and B play 15 games of cricket, of which 6 are won by A, 7 are won by team B, and 2 end in a tie. They agree to play a tournament consisting of 3 games. Find the probability that (i) A will win all the three games (ii) B will win at least 2 game.
