100 percent since they are the only chips avaliable

but if you meant both sepreatly
probability= portion/whole
then for the red chips=40/60=2/3
and the black chips =20/60=1/3

What is the answer to triple a number is the s game as double the number increased by 5
kramer

Answer:

x = 7

Step-by-step explanation:

Let x = the number. Then

                               "Triple a number" means 3x

                                  "is the same as" means =

"double the number increased by 5" means 2x + 7

∴ 3x = 2x + 7

Subtract 2x from each side

x = 7

The answer is x = 7.

Check:

3 × 7 = 2 × 7 + 7

     21 = 14 + 7

     21 = 21

OK.
