Hello,
Very nice as problem.
2 solutions:

Answer:
Angular velocity:
(
)
Linear velocity:
(
)
Step-by-step explanation:
The gear experiments a pure rotation with axis passing through its center, the angular (
), in radians per second, and linear velocities (
), in inches per second, of a point on the outer edge of the element are, respectively:
(1)
(2)
Where:
- Rotation rate, in revolutions per minute.
- Radius of the gear, in inches.
If we know that
and
, then the linear and angular velocities of the gear are, respectively:
![\omega = \frac{2\pi}{60}\cdot \dot n](https://tex.z-dn.net/?f=%5Comega%20%3D%20%5Cfrac%7B2%5Cpi%7D%7B60%7D%5Ccdot%20%5Cdot%20n)

![v = R\cdot \omega](https://tex.z-dn.net/?f=v%20%3D%20R%5Ccdot%20%5Comega)

Answer: The answer would be 13/25
Since there are 25 balls and 12 black balls, you want to subtract 12 from 25 to get the number of blue balls. There are 25 balls in total, so the probability of getting a blue ball is 13/25
