A box has 6 black, 4 red, 2 white and 3 blue shirts. What is probability of picking at least 1 red shirt in 4 shirts that are randomly picked?
- 69/91
- 68/91
- 70/91
- None of these
Explanation
Total = 15 shirts, red = 4, non-red = 11
P(no red) = 11/15 × 10/14 × 9/13 × 8/12 = 22/91
P(at least 1 red) = 1 - 22/91 = 69/91
