You can put this solution on YOUR website! Three numbers are chosen at random without replacement from the set {0, 1, 2, 3, ... , 10}. Calculate the probabilities that for the three numbers drawn
i) None will be greater than 7
# of ways to succeed:: 7
# of possible outcomes:: 11
P(condition) = 7/11
-------------------------
ii) the smallest will be 7
# of ways to succeed:: 4
# of possible outcomes:: 11
P(condition) = 4/11
=====================================
iii) the sum is equal to 7
Same procedure as above.
