Which ratio best defines theoretical probability?
2 answers:
Answer: Second option is correct.
Step-by-step explanation:
Since we know that Theoretical probability is the ratio of the number of favorable outcomes to the number of possible outcomes.
It means the possibility of favorable outcome out of all possible outcomes.
Mathematically, it is expressed as :
Hence, Second option is correct.

We must find the area of each cake's top.
Formula for area of a circle:
where r is the radius.
<span>small cake:
</span>Plug in 4 for r because the radius is 4. (They give us the diameter, which is 8, and the radius is half that)
A = 16π
<span>big cake:
</span>Repeat the process:
Plug in 12 for r because the radius is 12. (They give us the diameter, which is 24, and the radius is half that)
A = 144π
So our two radii are 144π and 16π.
The large cake's top is not 3 times the area of the small cake's.
This makes sense because you are squaring the radius, which makes the fact that the larger cake's diameter is triple the smaller cake diameter irrelevant.
