The probability that in a random sample of 1,500 people, more than 45 of them has gray eyes is 0.0028.
<h3>
Probability:</h3>
First step is to find the mean
Mean(μ) = np = (0.02) (1500)
Mean(μ) = 30
Second step is to find the standard deviation
Standard deviation (σ)= √(npq)
Standard deviation (σ)= √(0.02 × 0.98 × 1500)
Standard deviation (σ)= 5.42
Third step is to find the z-score
z-score = (x − μ) / σ
z-score = (45 − 30) / 5.42
z-score = 2.77
Fourth step is to find the probability
Where:
P=Probability
P(z > 2.77) = 1 − P(z < 2.77)]
P(z > 2.77) = 1 − 0.9972
P(z > 2.77) =0.0028
Inconclusion the probability that in a random sample of 1,500 people, more than 45 of them has gray eyes is 0.0028.

Answer:
The right answer is the function.
If we take as an example the different cells of the human body:
Macrophages are phagocytic cells, so it has more lysosomes and peroxisomes than other cells.
Plasma cells produce a huge amount of antibodies so their nucleus, endoplasmic reticulum and Golgi apparatus are highly developed.
Muscle cells are very active cells, so they have a large number of mitochondria.
The adipocytes have the role of storing fat, and for that, they have large vacuoles ...
