The control group and the dependent variable are respectively; will be the 3 dishes placed on the road not under construction and the 3 dishes placed on the road construction site

<h3>What is a control Group?</h3>

A control group in an experiment is that which is made up of participants that do not receive the experimental treatment.

From the opening paragraph, it means when we are conducting an experiment, these people in the control group are randomly assigned to be in this group and as such they also closely resemble the participants or the individuals who receive the treatment.

In this question, the control group will be the 3 dishes placed on the road not under construction

The dependent variable is one that depends on other variables or constraints in an experiment. In this question the dependent variable will be the 3 dishes that were placed in the road under construction.

10. The probability of a new york teenager owning a skateboard is 0. 37; of owning a bicycle is 0. 36 and of owning both is 0. 2
antoniya [11.8K]

The probability of the teenager owning a skateboard or a bicycle will be 0.46 or 46%. And the events are mutually exclusive.

<h3>What is the addition rule of size for two subsets?</h3>

For two subsets A and B of the universal set U, we have:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

The probability of a new york teenager owning a skateboard is 0.37, of owning a bicycle is 0.36, and of owning both is 0.27.

Then the probability of the teenager owning a skateboard or a bicycle will be

P(A ∪ B) = 0.37 + 0.36 - 0.27

P(A ∪ B) = 0.73 - 0.27

P(A ∪ B) = 0.46

Thus, the probability of the teenager owning a skateboard or a bicycle will be 0.46 or 46%.

The events are mutually exclusive.
