Answer:

You can't use a uniform probability model because that would require each item to have an equal chance.

Explanation:

11/44 b (25%)

18/44 o (40.91%)

15/44 p (34.09%)

As you can see, they aren't an equal chance.

The volume of a conical pile of sand is increasing at a rate of 300πcm3/sec
lesya [120]
So using the formula for the volume of a cone:
r^2pi x h/3

The height is always 4 times the radius, so:
h=4r

Now putting the values into the original formula:

r^2pi x 4r/3

Now to see how much the radius increases per second:

r^2pi x 4r/3=300pi

r^2 x 4r/3=300

r^2 x 4r=900

r^2 x r=225

r^3=225

The radius increases by the cubic square root of 225 cm per second.

f(s)= 225^1/3 cm
