Respuesta :

Given:

The probability of occurence of students in white, Non-Hispanic ethnicity is 0.7833.

The number of students = 5.

Let A be an event of choosing atleast one student of white, Non-Hispanic ethnicity.

The sample space for this event = 5

The number of students in white, Non-Hispanic ethnicity.

[tex]n(A)=5\times0.7833[/tex]

[tex]n(A)=3.9165[/tex]

The probability of choosing at least one student of White, Non-Hispanic ethnicity

[tex]P(A)=\frac{n(A)}{n(S)}[/tex][tex]P(A)=\frac{3.9165}{5}=0.7833[/tex]

The probability of choosing at least one student of White, Non-Hispanic ethnicity is 0.7833.
