The blood groups of 30 students of class IX are recorded as follows: A, B O, O, AB, O, A, O, B, A, O, B, A, O, O, A, AB, O, A, A, O, O, AB, B, A, O, B, A, B, O A student is selected at random from the class from blood donation. Find the probability that the blood group of the student chosen is: (i) A (ii) B (iii) AB (iv) O

The possible blood group of children born to parents having A and AB blood groups are: a) O, A b) A, B, AB c) B,O, A d) O, A, B, AB

if vec Ao + vec O B = vec B O + vec O C ,than prove that B is the midpoint of AC.

A,B and O blood groups were discovered by

Give an example of two matrices A and B such that A!=O ,\ \ B!=O ,\ \ A B=O and B A!=O (ii) A!=O ,\ \ B!=O ,\ \ A B=B A=O .

The blood groups A, B, AB and O are classified on the basis of the type of antigen present on

if vec (AO) + vec (O B) = vec (B O) + vec (O C) ,than prove that B is the midpoint of AC .

O is any point in the interior of A B Cdot Prove that A B+A C > O B+O C A B+B C+C A > O A+O B+O C O A+O B+O C >1/2(A B+B C+C A)

If vec A O+ vec O B= vec B O+ vec O C , prove that A , B , C are collinear points.
