Question 330304
Hello Can someone advise if this right. I hope I used the correct formula 
In how many ways you can randomly select 5 students from a 12-student class? 
ANS: 12C5 = (12*11*10*9*8)/(1*2*3*4*5) = 792
<pre><b><font size = 4><b>
That's correct!
</pre></b></font>
Also Can some please advise on the below item I answered question B but I am not the greatest with Sample Space. 
Consider the probability experiment of drawing one card from a deck of cards. 
a) Determine the sample space of the probability experiment. 
ANS: 
<pre><b><font>
<font color = "red" size = 4>
 
{A&#9829;  2&#9829;   3&#9829;   4&#9829;   5&#9829;   6&#9829;   7&#9829;   8&#9829;  9&#9829;  10&#9829;  J&#9829;  Q&#9829;  K&#9829; 

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 color = "black">

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 the sample space.  It contains 52 cards.

The probability of drawing a face card is found by counting the successful
ways to get a face card, which is these 12:

{J&#9829;  Q&#9829;  K&#9829; 

J&#9830;  Q&#9830;  K&#9830;<font color = "black">

J&#9824;  Q&#9824;  K&#9824;
  
J&#9827;  Q&#9827;  K&#9827;}

ways out of the 52 in the sample space or {{{12/52}}} 

which reduces to {{{3/13}}}
