(Round your answer to four decimal places)

Answer 1

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.
