Plotting Two probability distribution functions on a single image

Hi all I have two series data named A & B. I want to plot their probability distribution functions (pdf) through a single image. How can I do it.

A=[ 232  241  147  230  407  335  315  256  254  131  449  605  212  283  293];

B=[ 118  135  77  79  163  192  155  113  101  74  223  317  84  129  116];

Any help would be appreciated Cheers,
