Answer:

[tex]P(k)=0.2628[/tex]

Step-by-step explanation:

Given

[tex]n = 1693[/tex] --- sample size

[tex]k = 445[/tex] --- those that prefer chocolate ice cream to vanilla

Required

[tex]P(k)[/tex]

This is calculated as:

[tex]P(k)=\frac{k}{n}[/tex] --- probability formula

So, we have:

[tex]P(k)=\frac{445}{1693}[/tex]

[tex]P(k)=0.2628[/tex]
