Answer:
0% probability that 3 of them have insurance
Step-by-step explanation:
For each American, there are only two possible outcomes. Either they have insurance, or they do not. 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.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Twenty-percent (20%) of Americans have no health insurance.
This means that 80% have insurance, so
Randomly sample n = 15 Americans.
This means that
What is the probability that 3 of them have insurance?
This is
0% probability that 3 of them have insurance
Answer:
Step-by-step explanation:
10 diget number
$10 per shirt because each shirt cost $10.
A line that the graph of a function approaches but never touches.
Answer:
equilateral triangle all angles add up to 180 and are equal so each angle is 60 degrees
angles on a line add up to 180.
angle CBD = 180-60 = 120
DBC is an isosceles triangle so it's base angles are the same.
180-120= 60
60/2=30
