The function shown in figure, can represent a probability density function for A __________

A A = 1/4

B A = 1/6

C A = 1/9

D A = 1/2

ANS:C - A = 1/9

The condition for the probability density function d(x) isand is always non negative or the area under the curve f(x)is unity. => A x 6 +x 2 x 3A = 1 or 9A = 1 or A =.
