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.

Answer:
A balance and a graduated cylinder.
Explanation:
<u><em>Density</em></u> is the relationship between mass and volume of a substance, the formula is:
ρ
Where m is the substance mass, and v is the volume.
If a student wants to measure the density of seawater, he or she should use a Balance, to measure the mass of the sample. And then use a Graduated cylinder, is a volumetric instrument that allows to contain liquids and then measures the exact volume of the sample.
Once the student obtains the mass and the volume, he/she has to replace the data in the density formula and so obtain the density of seawater.
Answer:
Katie Ledecky started the "Dive into STEM Education" because she wanted children to focus on studying the subjects o<u>f Science, Technology, Engineering and Mathematics (STEM).</u>
I know this because Katie stated this when <em>she became a spokesperson during her visit in Las Vegas. </em>She even said<em> "Education has always been front and center in my life."</em>
