The probability that a sample of size n will have a mean,
, less that a given value, X, where the population mean,
, and the population standard deviation,
, is known is given by:
Therefore, the required probability is given by:
You could do 2/6+2/6=4/6, or you could do 1/6+3/6=4/6, or vice versa.
The distance around the outside a circle is its circumference. Consider the formula for the circumference of a circle, Circumference = Pi x Diameter. Solving for Pi we get, Pi = Circumference divided by Diameter.
Given:
Height of cone = 3 cm
Radius of cone = diameter ÷ 2 = 16 cm ÷ 2 = 8 cm
To be able to get the volume of the cone, we will be using the following formula:
We get,
Therefore, the volume of the cone is 192 cm
