Answer:
2:1
Step-by-step explanation:
Circle P has radius 14 feet.
The circumference of this circle is given by:

We plug in the radius to get:

Circle Q has diameter 14 feet.
The circumference of this circle is given by

We substitute the diameter d=14 to get,


The ratio of the circumference of P to the circumference of Q is

3+5+7 = 15 total marbles
3 are red
so she has a 3/15 reduces to 1/5 probability of picking a red one
