Answer:
0
Step-by-step explanation:
Numbers on balls:
1, 4, 7, 7, 8
Try to find the sum of all numbers:
1+4+7+7+8 = 27
According to the rule of 3, any number is dividable by 3 if the sum of it's individual is divided by 3.
27 is dividable by 3, therefore any combination will result a number with a factor of three.
Prime number is the number that is only dividable by 1 and itself. Therefore, any combination using those numbers are not prime number.
So the probability is 0
subtract 2x from both sides... 6x=2 divide by 6 = .3
Reliable causal inference based on observational studies is seriously threatened by unmeasured confounding.
What is unmeasured cofounding?
- By definition, an unmeasured confounder is a variable that is connected to both the exposed and the result and could explain the apparent observed link.
- The validity of interpretation in observational studies is threatened by unmeasured confounding. The use of negative control group to reduce unmeasured confounding has grown in acceptance and popularity in recent years.
Although they've been utilised mostly for bias detection, negative controls have a long history in laboratory sciences and epidemiology of ruling out non-causal causes. A pair of negative control exposure and outcome variables can be utilised to non-parametrically determine the average treatment effect (ATE) from observational data that is vulnerable to uncontrolled confounding, according to a recent study by Miao and colleagues.
