6(c+8)-4c —> 2(3(c+8)-2x) —> 2(3x+24-2x) —> 2(x+24) is the equivalent expression

Answer:

0.0367 = 3.67% probability that exactly 6 patients will die

Step-by-step explanation:

The patients are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question, we have that:

20 patients means that $N = 20$

Sample of 8 means that $n = 8$

9 have the heart problem, so $k = 9$

What is the probability that exactly 6 patients will die?

This is P(X = 6).

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 6) = h(6,20,8,9) = \frac{C_{9,6}*C_{11,2}}{C_{20,8}} = 0.0367$

0.0367 = 3.67% probability that exactly 6 patients will die

MaRussiya [10]

Whatever the geometric shape, I don't even need to know the shapes of the items involved.
If all linear dimensions are 6 times smaller, then all volumes will be 216 times smaller a scale model

the answer is 6^3 = 216 times smaller
