Question

PLZZZZ HELPPPPPPPPP!!!! a survey asks teachers and students whether they would like the new school mascot to be a Viking or a Patriot. this table shows the results

Answer 1

B

Explanation:

Two events A and B are called independent, when

`P(B|A)=P(B),`

where
`P(B|A)` is the probability that B occurs given that A has already occurred.

A = randomly selected person is a student

B = randomly selected person prefer "Vikings"

B|A = randomly selected student prefer "Vikings"

Probabilities:

`P(A)=(100)/(125)=(4)/(5)=0.8\\ \\P(B|A)=(80)/(85)=(16)/(17)\approx 0.94`

Since

`0.80\\eq 0.94`

we can state that events are not independent.
