Question

9. A bag contains 8 blue chips, 7 green chips and 2 white chips. If two chips are
drawn without replacement, what is the probability of drawing a blue chip
and a green chip?

Answer 1

Answer:

7/34

Step-by-step explanation:

Total number of chips in the bag = 8 + 7 + 2 = 17

⇒ P(blue) = 8/17

⇒ P(green) = 7/16 (since the first chip has not been replaced)

⇒ P(blue and green) = 8/17 x 7/16 = 7/34
