In a large population, 60% of the people have been vaccinated. If 4 people are randomly selected, what is the probability that AT LEAST ONE of them has been vaccinated?
Give your answer as a decimal to 4 places.
Answer:
0.9744 probability that AT LEAST ONE of them has been vaccinated
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they have been vaccinated, or they have not. The probability of a person having been vaccinated is independent of any other person. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
60% of the people have been vaccinated.
This means that [tex]p = 0.6[/tex]
If 4 people are randomly selected, what is the probability that AT LEAST ONE of them has been vaccinated?
This is
[tex]P(X \geq 1)[/tex] when [tex]n = 4[/tex].
We have that
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{4,0}.(0.6)^{0}.(0.4)^{4} = 0.0256[/tex]
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.0256 = 0.9744[/tex]
0.9744 probability that AT LEAST ONE of them has been vaccinated

How do I solve this equation?
Answer:
n=3
Step-by-step explanation:
distribute, then add 3 to both sides, then divide both sides by 3
Answer:
n = 3
Step-by-step explanation:
3(n−1)=6
Step 1: Simplify both sides of the equation.
3(n−1)=6
(3)(n)+(3)(−1)=6(Distribute)
3n+−3=6
3n−3=6
Step 2: Add 3 to both sides.
3n−3+3=6+3
3n=9
Step 3: Divide both sides by 3.
3n/3 = 9/3\
n= 3

[tex]\frac{1}{7}+\frac{1}{2}[/tex]
Least common multiple of 7 and 2 is 14. Convert [tex]\frac{1}{7} and \frac{1}{2}[/tex] to fractions with denominator 14.
[tex]\frac{2}{14} + \frac{7}{14}[/tex]

[tex]\frac{2+7}{14}[/tex]
Add 2 and 7 to get 9.

Brady is conducting an experiment using a spinner with four different colors: red, orange, blue, and green. He spun the spinner 40 times and recorded the following data.
Based on the data in the table, if Brady spins the spinner 240 times, he predicts the spinner will land on red roughly A. 48, B. 24, C. 12, D. 36 times. He also predicts the spinner will land on green roughly A. 108, B. 72, C. 48, D. 36
more times than it will land on red.
Answer:
out of 240, the prediction of landing on Red would be 36
out of 240, the prediction of landing on Green would be 108
Step-by-step explanation:
out of 240, the prediction of landing on Red would be 36 because:
240 x 0.15 = 36
out of 240, the prediction of landing on Green would be 108 because:
240 x 0.45 = 108

What's the slope of a line that passes through (−12,15) and (0,4)?
Answer:
-11/12
Step-by-step explanation:
slope for points (x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)
(x,y)
(-12,15)
(0,4)
x1=-12
y1=15
x2=0
y2=4
slope=(4-15)/(0-(-12))=-11/(0+12)=-11/12
Answer:
Slope: -11/12x
Step-by-step explanation:
Slope-intercept equation:
y = mx + b
(m = slope)
The formula for slope is below.
m = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
With your two points, you can accurately determine your slope.
(-12, 15) (0,4)
x1 = -12
y1 = 15
x2 = 0
y2 = 4
Apply this information in the slope formula to get:
[tex]\frac{4 - 15}{0 - -12}[/tex]
Change the 0 - -12 to 0 + 12
[tex]\frac{4 - 15}{0 + 12}[/tex]
4 - 15 = -11
0 + 12 = 12
Place -11 and 12 into a fraction.
[tex]\frac{-11}{12}[/tex] OR -11/12
Add "x" to the end from "mx" within the slope-intercept equation
-11/12x
