red crayon?

Answer 1

Answer:

1/6

Step-by-step explanation:

Simply just Add the different amounts of different crayons as your denominator, and find the number of red, as your numerator. This gets you 2/12. 2/12 = 1/6

Answer 2

Answer:

1/36

Step-by-step explanation:

We have 12 Crayons total

2 of those are red

So the chance of pulling one red is 2/12

If we have to find the chance of two thing happening (Getting two reds back to back) we have to multiply our chances. Think of how its harder to get the same thing twice in a row.

So its 2/12 × 2/12 = 4/144

Simplify and get 1/ 36
