Question 768724
A card is drawn from a standard deck of 52 playing cards. what is the probability that the card is a spade and not a face card?
<pre>
That's the probability that we draw one of the these 10
cards that is a spade but not a face card:

A&#9824;   2&#9824;   3&#9824;   4&#9824;   5&#9824;   6&#9824;   7&#9824;   8&#9824;  9&#9824;  10&#9824;

out of these 52:

A&#9830;   2&#9830;   3&#9830;   4&#9830;   5&#9830;   6&#9830;   7&#9830;   8&#9830;  9&#9830;  10&#9830;  J&#9830;  Q&#9830;  K&#9830;</font>
A&#9824;   2&#9824;   3&#9824;   4&#9824;   5&#9824;   6&#9824;   7&#9824;   8&#9824;  9&#9824;  10&#9824;  J&#9824;  Q&#9824;  K&#9824;  
A&#9827;   2&#9827;   3&#9827;   4&#9827;   5&#9827;   6&#9827;   7&#9827;   8&#9827;  9&#9827;  10&#9827;  J&#9827;  Q&#9827;  K&#9827; 

That's a probability of 10 out ot 52.

In probability, "out of" means "over", so

the probability is 10 over 52 or {{{10/52}}}

which reduces to {{{5/26}}}
