Question

Hey @Vocaloid am I dumb or does the radius not matter.

Answer 1

Keep in mind it says "each slice has area 1/6" not "each slice has area 1/6 of the whole circle"

so the area has to be *exactly* 1, which means there's only one possibility for the radius

Answer 2

I think it's kind of a dumb example but it's just showing that probability distributions have to add to 1

Answer 3

like, the area has to equal the number "1" not "1 whole"

Answer 4

Yeah he literally has 'represents 1/6' followed by 'has area 1/6.' Like I thought it could be an abstract 1/6 of the circle.

So \[A = \pi r^2\]
\[1 = p ir^2\]
\[r = \sqrt \frac{ 1 }{ \pi } \rightarrow 0.564\]

Answer 5

yeah that's what i got too

Answer 6

coolio, ty <3
