Consider the following probability distribution for stocks A and B:

State Probability Return on Stock A Return on Stock B

$10\mathrm{.}1010\%8\%$

$20\mathrm{.}2013\%7\%$

$30\mathrm{.}2012\%6\%$

$40\mathrm{.}3014\%9\%$

$50\mathrm{.}2015\%8\%$

The coefficient of correlation between A and B is:

and B are $\_\_\_\_\_$blank and $\_\_\_\_\_$blank, respectively.
