Answer:
H. 1/9.
Step-by-step explanation:
The area of a circle is calculated by solving for π.
The smallest circle has an area of π = π * 1 = π.
The middle ring will then have an area of π - π = π * 4 - π = 4π - π = 3π.
The largest ring will then have an area of π - π
= 9π - 4π = 5π.
5π + 3π + π = 9π
So, the probability of hitting the innermost circle will be π / 9π = 1 / 9.
Your answer is H. 1/9.
Hope this helps!
