Question 1137395
In a {{{52 }}}card deck there are {{{4}}} suits, so {{{52}}} divided by {{{4}}} is {{{13}}}.

Hence there are {{{13}}} hearts. 

{{{52 }}}minus {{{13}}} is{{{ 39}}}, so there are {{{39}}} cards that are{{{ not}}} hearts. 

So if drawing a {{{heart}}} is considered a {{{favorable}}}{{{ outcome}}}, then there are {{{13 }}}possible {{{favorable }}}{{{outcomes}}}, and there are {{{39}}} possible {{{unfavorable}}}{{{ outcomes}}}. 

Hence, the odds in favor of drawing a heart are {{{13/ 39}}}. 

But notice that both {{{13}}} and {{{39}}} are evenly divisible by {{{13}}}, so reduced to lowest terms we have {{{highlight(1/3)}}}.
