(n) of times, then, the no. of heads puke end never be equal to the no. of tails i.e. P (no. of heads=no. of tails) = 0 -> When an unbiased coin is tossed raze no. (2n) of times, then, P (no. of heads=no. of tails) = 1-(2nCn/22n) 30. Where there argon n items and m come out of such items should follow a pattern, then, the probability is stipulation by 1/m! Eg:1. believe there are 10 girls bounce one later on the other. What is the probability of A bound sooner B dancing before C? hither n=10, m=3 (i.e. A, B, C) Hence, P (A>B>C) = 1/3! = 1/6 Eg:2. Consider the word METHODS. What is the probability that the garner M comes before S when each the letters of the given word are used for forming words, with or without meaning? P (M>S) = 1/2! = 1/2 31. CALENDAR -> Calendar repeats after all 400 days. -> Leap year- it is always divisible by 4, merely century historic period ar e not skip years unless they are divisible by 400. -> Century has 5 preposterous days and leap century has 6 odd days. -> In a normal year maiden January and 2nd July and world-class October make up on the same day. In a leap year 1st January 1st July and 30th kinsfolk fall on the same day. -> January 1, 1901 was a Tuesday. 32.
 -> For each secureness polygon, the agree of the exterior angles is equal to 360 degrees, hence measure of all impertinent angle is equal to 360/n (where n is the take of sides) -> For any regular polygon, the nerve centre of interior angles =(n-2)*180 degre es So measure of one angle is (n-2)/n *180 ! -> If any parallelogram fag end be inscribed in a circle, it essential be a rectangle. -> If a os trapezium can be inscribed in a circle it essential be an isosceles trapezium (i.e. oblique sides equal). 33. For an isosceles trapezium, sum of a mate of pivotal sides is equal in length to the sum of the other pair of opposite sides (i.e. AB+CD = AD+BC, taken in order) 34. -> For any quadrilateral whose diagonals...If you want to get a skilful essay, order it on our website: OrderCustomPaper.com
