Question 1092397: suppose 4 cards are drawn from a well shuffeld deck of 52 cards what is the probability that all are black cards?
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! Assuming sampling without replacement, 1/2 is the first probability, 25/51 the second, 24/50 the third, and 23/49 the fourth.
This is 0.0552
Can check using sampling with replacement which would increase the probability to (1/2)^4=(1/16)=0.0625.
The answer above is reasonable.
