a.
To calculate: The number of possible combinations of five people who squeeze toothpaste from the middle of the tube.
The resultant answer is 8,568 ways.
Given information:
The given bar graph shows the results of 40 responses to a survey:
Formula used: If
Calculation:
From the graph, it can be seen that 45 percent of 40 squeeze toothpaste from the middle:
The number of ways in which 5 people can be selected from a group of 18 people,
Rewrite the expression using the formula
Now expand the factorial,
Therefore, there are 8568 number of ways in which 5 people can be selected from a group of 18 people.
b.
To calculate: The number of possible combinations of five people if five people are chosen at random from all the people who responded to the survey.
The resultant answer is
Given information:
Total people participated in the survey is 40.
Formula used: If
Calculation:
The number of ways in which 5 people can be selected from a group of 40 people,
Rewrite the expression using the formula
Now expand the factorial,
Therefore, there are
