A bag contains 2 red and 4 green sweets of the same size and shape….

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?

  • A.
    (frac{1}{5})
  • B.
    (frac{2}{5})
  • C.
    (frac{8}{15})
  • D.
    (frac{14}{15})
Correct Answer: Option D
Explanation

P(at least one green wrapper) = 1 – P(no green wrapper)

= (1 – (frac{2}{6} times frac{1}{5}))

= (1 – frac{1}{15})

= (frac{14}{15})
