Determine the odds of choosing 4 aces when drawing 4 cards randomly from a regular deck of cards.
Answered by Macy
I tried to use the formula p(a)/p(a') but I don't know how to find the p(a) and p(a') values^
Answered by Steve
p(1st ace)=4/52
p(2nd ace)=3/51
...
p(all 4 aces)= (4*3*2*1)/(52*51*50*49) = 4!/(52P4) = 1/(52C4) = 1/270725
so, the odds are 1:270724
