Answer 1

Answer:

The probability that the person will not  be a senior

P(E⁻) = 1 - P(E)

       =  $1- \frac{5}{9} = \frac{4}{9}$

Step-by-step explanation:

Explanation:-

Given A high school club has 10 members who are seniors and 8 members who  are juniors

n(S) = 10 + 8 = 18

If a member is randomly selected to be the club president

Let 'E' be the event that the person will  be a senior

The probability that the person will  be a senior

      $P(E) = \frac{n(E)}{n(S)}$

     $P(E) = \frac{n(E)}{n(S)} = \frac{10}{18} = \frac{5}{9}$

The probability that the person will not  be a senior

P(E⁻) = 1 - P(E)

       =  $1- \frac{5}{9} = \frac{4}{9}$
