A bag contains 3 red, 3 green and 4 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? Options.
A) 5/8	B) 7/12	C) 11/16	D) 17/24	E) 37/48
P(no red balls) = 7/10*6/9*5/8 = 7/24   P(at least one red ball) = 1 - 7/24 = 17/24   The answer is 17/24.
