Using the hypergeometric distribution, it is found that the probability is 0.845 = 84.5%.
--------------------
- The patients are chosen from the sample without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x successes is given by:

The parameters are:
- x is the number of successes.
- N is the size of the population.
- n is the size of the sample.
- k is the total number of desired outcomes.
Combination formula:
is the number of different combinations of x objects from a set of n elements, given as:

--------------------
- 56074 patients, thus

- Sample of 40, thus,

- 235 left against medical advice, thus,
.
The probability that none left against medical advice is P(X = 0), so:


The probability is 0.845 = 84.5%.

Answer:
The New England colonies had rocky soil, which was not suited to plantation farming, so the New England colonies depended on fishing, lumbering, and subsistence farming.
Answer:
Based on Pauling Scale, electro negativity of Cl = 3.2, Na = 0.9 and H = 2.1
Explanation:
Thus, Electronegativity difference in Cl2 = 3.2 -3.2 = 0
Electronegativity difference in NaCl = 3.2-0.9 = 2.3
Similarly, Electronegativity difference in HCl = 3.2 - 2.1 = 1.1
Thus, among the listed molecules following is the decreasing order of electronegativity difference: NaCl> HCl > Cl2
