<em><u>Solution:</u></em>
Given that,
Suppose that a vaccine is 85% effective against the flu
You vaccinated 6 people
To find: Number of people you expect will be protected from the virus
From given,
85 % of 6 people are effective against the flu
Which means,
Thus, 5 of the 6 vaccinated people will be protected from the virus
Answer:
7 and the corresponding angle theorem
Step-by-step explanation:
Using the binomial distribution, the probabilities are given as follows:
a) 0.4159 = 41.59%.
b) 0.5610 = 56.10%.
c) 0.8549 = 85.49%.
<h3>What is the binomial distribution formula?</h3>The formula is:
The parameters are:
For this problem, the values of the parameters are:
n = 3, p = 0.76.
Item a:
The probability is P(X = 2), hence:
Item b:
The probability is P(X < 3), hence:
P(X < 3) = 1 - P(X = 3)
In which:
Then:
P(X < 3) = 1 - P(X = 3) = 1 - 0.4390 = 0.5610 = 56.10%.
Item c:
The probability is:
