A bag contains 2 red and 4 green sweets of the same size and shape. Two boys pick a sweet each from the box, one after the other, without replacement. What is the probability that at least a sweet with green wrapper is picked?
15
25
815
1415
Correct answer is D
P(at least one green wrapper) = 1 - P(no green wrapper)
= 1−(26×15)
= 1−115
= 1415
