Answer 1

Red or blue crayon - 11/16

Explanation:

Red or blue crayon - 11/16

Answer 2

`(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.
