A bag contains 2 red, 2 green, and 3 white balls. Three balls are picked up one by one without replacement. What is the probability that there will be at least one red ball? Choose the correct choice from the following options:
A) 5/7  B) 11/14  C) 17/21  D) 19/28  E) 23/35
P(no red balls) = 5/7*4/6*3/5 = 2/7   P(at least one red ball) = 1 - 2/7 = 5/7   The answer is 5/7.
