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.


n(A)=5*0.7833


n(A)=3.9165

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


P(A)=(n(A))/(n(S))
P(A)=(3.9165)/(5)=0.7833

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