When the correlation between X and Y is strong, the central limit theorem ensures that the application of your relationship between the two variables even in the absence of a linear trend. a) true
b) false

  D:  75%

Step-by-step explanation:

The figure is not drawn to scale, so can be misleading.

The ratio of smaller circle radius to larger circle radius is ...

  2/4 = 1/2

The ratio of smaller circle area to larger circle area is the square of this:

  (1/2)^2 = 1/4

Then the white circle is 1 -1/4 = 3/4 of the total area. The probability it will be hit by a dart is 3/4 = 0.75 = 75%.

The probability of hitting the white part of the circle is 75%.
