Question 1154194

If odds are stated as an {{{A}}} to {{{B}}} chance of winning then the probability of winning is given as {{{PW = A / (A + B)}}} while the probability of losing is given as {{{PL = B / (A + B)}}}

you are given {{{A=13}}} and {{{B=28}}}

the probability of winning is 
{{{PW = 13 / (13+ 28)}}} 
{{{PW = 13 / 41}}} 
{{{PW = 0.3171}}}  or {{{31.71}}}%


the probability of losing is 

 {{{PL = B / (A + B)}}}

{{{PL = 28 / (13 + 28)}}}

{{{PL = 28 / 41}}}

{{{PL = 0.6829}}} or {{{68.29}}}%
