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.

The given situation represents the example of a clinical/case study of the research method.
<h3>What is a clinical/case study?</h3>
A clinical case study refers to the case study where the doctors share the cases of patients that are not common or not explained before. In this, the permission of the patient should be required for writing the report on the clinical case.
Hence, we can conclude that The given situation represents the example of a clinical/case study of research method.

2W+2L=66
W=1/2L
2(1/2L)+2L=66
Simplifies to L+2L=66
Simplifies to 3L=66
Or L=22.
If W=1/2L, then W =1/2(22).
W=11.
To check our work, 2W+2L=66.
2(11)+2(22)=66.
22+44=66
66=66 Check.
