$V_{1} = \frac{1}{3} * \pi * r^{2}* h= \frac{3.14* 24^{2} *6}{3} =3617.28 \\ V_{2} = \pi * r^{2}* h \\ 3617.28=3.14* 16^{2} *h \\ h= \frac{3617.28}{3.14* 16^{2}} =4.5$

A survey found that 25% of pet owners had their pets bathed proffesionally rather than doing it themselves. If 18 pet owners are

AveGali [126]

The probability is 19.88%.

This is a binomial distribution, because there are two outcomes, the events are independent of each other, and there is a fixed number of trials. The binomial distribution is given by:

$(_k^n)p^k(1-p)^{n-k}$

For this, n is 18; k is 5; p is 0.25:
$(_5^{18})(0.25)^5(1-0.25)^{18-5}
\\
\\=\frac{18!}{5!13!}(0.25)^5(0.75)^{13}
\\
\\=8568(0.25)^5(0.75)^{13}
\\=0.1988=19.88%$
