Part c

The probability that the first slice of the cake will have the marble exists

7/66.

<h3>How to determine the probability using parts A and B?</h3>

Part A of the question demands that the volume of the cake be

estimated.

The volume of the cake exists, $V=\pi(\frac{d}{2} )^{2} h \\

$&V=\pi(\frac{9}{2} )^{2} * 4

$V=81 \pi

The part B of the question requires that the volume of each cut be

computed

The volume of each cut exists, V = 27

To estimate the required probability

We simply divide the volume of each cut by the volume of the cake.

$P=\frac{27}{81 \pi}

$P=\frac{1}{3 \pi}

Expand $\pi$

$&P=\frac{7}{3 * 22} \\

$&P=\frac{7}{66}

Therefore, the probability that the first slice of the cake will contain the

marble exists at 7/66.
