Answer:


(1)/(2)

Explanation:

  • There are 24 total crayons in the box.
  • You want to know the probability of picking a blue or yellow crayon.
  • Since there are 7 yellow crayons and 5 blue you add those together and get 12.
  • You now have your numerator in your fraction. There are also 12 red crayons
  • 12+12 = 24 and now you have your denominator.
  • The fraction now reads 12/24.
  • You simplify by dividing the top and bottom by 12 and get 1/2.
  • Hope this helps.
