Answer:
A, D and E
Step-by-step explanation:
Given are the graphs of some functions and we have to find which are the density functions.
Since total probability is always 1, area under the curve must be equal to 1.
APplyig this we find that graph B cannot be density function.
Since probability is non negative graph C cannot be probability density function.
A, D and E are the density graphs.
w=32
w/4 = 8
4/1 * w/4 = 8*4
