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
$4.40
2 ÷ 5= 2/5 = .4 pounds or 2/5 of a pound per friend
<u>Answer-</u>
<u>Solution-</u>
In the graph, on the abscissa time in hours is represented and on the ordinate the number of stones left is represented.
From the graph we have three points, they are (0, 55), (3, 40), (7, 20)
Taking any two points and applying two point formula of straight line, we can get the equation or relation between the two variables.
Taking (0, 55), (3, 40)
Therefore, 5x+y=55 is the correct relationship that represents the number of paving stones left to play y and the time x Gerald has spent working.
