The double square brackets have no specific meaning except in some context. They may be used for any of ...

  • nearest-integer function. [[3.4]] = 3; [[3.5]]= 4, for example
  • ceiling function. [[3.4]] = 4
  • floor function. [[3.6]] = 3
  • identification of matrix rows and columns. [[1, 2, 3][4, 5, 6]] is a matrix of two 3-column rows
  • norm function. [[3+4i]] = √(3²+4²) = 5

Check your math text for the definition it intends.

Brenda throws a dart at this square-shaped target: Part A: Is the probability of hitting the black circle inside the target clos
Masteriza [31]
Either way.  The probability of hitting the circle is:

P(C)=Area of circle divided by area of square

P(W)=(area of square minus area of circle divided by area of square

P(C)=(πr^2)/s^2

P(W)=(s^2-πr^2)/s^2

...

Okay with know dimensions, r=1 (because r=d/2 and d=2 so r=1), s=11 we have:

P(inside circle)=π/121  (≈0.0259  or 2.6%)

P(outside circel)=(121-π)/121  (≈0.9744 or 97.4%)
