Explanation:
P(different) = P(white then black) + P(black then white) = (5/8)(3/7) + (3/8)(5/7) = 15/56 + 15/56 = 30/56 = 15/28. This accounts for both orders of drawing.
Assertion (A): The median is a better measure of central tendency than the mean for ordinal data. Reason (R): The median is based on the rank order and is unaffected by the exact magnitude of differences. Choose the correct option:
A.Both A and R are true, but R is not the correct explanation of A
B.A is true, R is false
C.A is false, R is true
D.Both A and R are true, and R is the correct explanation of A
