Question 264890: Three integers are randomly selected without replacement from the
set { 1,2,3,5,6,7}. What is the probability that the mean of the values chosen is less than, but not equal to, 5? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Procedure:
There are 7C3 = 35 sets of 3 digits.
List them, determine the mean of each set, and count the number that meet the condition of the problem.
Note: The sum of the numbers must be <=15.
The P(condition met) = (# of sets that meet the condition)/35
