Calculate the relative frequency P(E) using the given information.
400 adults are polled and 320 of them support universal health care coverage. E is the event that an adult does not support universal health coverage.
P(E)=?
Where’d you get the 80 from?
To calculate the relative frequency P(E), we need to find the ratio of the number of adults who do not support universal health care coverage to the total number of adults polled.
Total number of adults polled = 400
Number of adults who do not support universal health care coverage = Total number of adults polled - Number of adults who support universal health care coverage
Number of adults who do not support universal health care coverage = 400 - 320 = 80
P(E) = Number of adults who do not support universal health care coverage / Total number of adults polled
P(E) = 80 / 400
P(E) = 0.2
Therefore, the relative frequency P(E) is 0.2 or 20%.
To calculate the relative frequency P(E), we need to divide the number of adults who support the opposite event (in this case, not supporting universal health care coverage) by the total number of adults polled.
Given that there are 400 adults polled and 320 of them support universal health care coverage, we can calculate the number of adults who do not support universal health care coverage:
Number of adults who do not support universal health care coverage = Total number of adults polled - Number of adults who support universal health care coverage
= 400 - 320
= 80
Now, we can calculate the relative frequency P(E):
P(E) = Number of adults who do not support universal health care coverage / Total number of adults polled
= 80 / 400
= 0.2
Therefore, the relative frequency P(E) is 0.2 or 20%.
assuming that they either supported it or not supported it,
P(E) = 80/400 = 1/5
